I attended the JMM to present my research project from the summer EE Just Program, which resulted in the creation of two AI models: one that detects heart disease and another that classifies brain tumours. The experience was incredibly exciting. It was inspiring to see so many people passionate about mathematics and its role in AI, both in development and safety. The conference sessions covered a wide range of topics, from highly technical mathematical talks to conversations about the future of mathematics as a profession amidst emerging technologies. I was surprised about the fact that there was a lecture by the Chief AI Scientist of Meta, who explained the limitations of current algorithms. This event was valuable not only for the knowledge shared but also for the sense of community and appreciation within the mathematical field. Additionally, the National Association of Mathematicians hosted a banquet focused on promoting inclusiveness and prosperity among minority groups in mathematics.

The work of former postdoc Dr. Han with professors Lee and Gelb, "Learning in-between imagery dynamics via physical latent spaces”, has been published in the SIAM Journal on Scientific Computing. The work proposes a framework to learn the underlying dynamics between two images observed at consecutive time steps. The proposed method focuses on estimating the intermediary stages of image evolution, allowing for interpretability through latent dynamics while preserving spatial correlations with the image. By incorporating a latent variable that follows a physical model expressed in partial differential equations, the approach ensures the interpretability of the learned model and provides insight into corresponding image dynamics. The work also provides a series of numerical tests, including real SAR data, to demonstrate the robustness and effectiveness of the new framework. Click the video below for higher resolution. More demonstrations (including videos) can be found here.

Second-year PhD student David Freeman, Professor Dimitris Giannakis, third-year PhD student Brian Mintz, and Professor Joanna Slawinska are authors of the paper Data assimilation in operator algebras, recently published in PNAS. The paper grew out of a collaboration with Slawinska and Abbas Ourmazd (University of Wisconsin–Milwaukee) on using techniques from ergodic theory and quantum mechanics to perform sequential data assimilation of partially observed dynamical systems, with applications in climate dynamics. In 2021 work by Giannakis, Freeman, and Mintz as part of graduate independent reading course furthered the research: “During that course and in the subsequent months, we developed a formulation that views data assimilation as information processing through a quantum channel associated with algebras of observables of the dynamical system,” says Giannakis. “Classical (Bayesian) and ‘quantum’ data assimilation correspond to abelian and non-abelian choices of that algebra, respectively, which we believe provides an interesting unified viewpoint that offers opportunities for new algorithms for forecasting dynamical systems.”

Hearty congratulations to all the organizers, mentors, and undergraduates who have participated in our department’s successful Directed Reading Program! A recent Dartmouth News story describes how graduate student Richard Haburcak founded the program in 2021 with the idea of it being inclusive from the start: “The DRP strives to increase diversity in mathematics and foster a supportive environment for students to explore mathematics,” says Haburcak. “We want to give students the chance to see math the way that mathematicians see math, to see the human side of math, and to be able to learn about topics that you usually don't have the chance to study until much later.” At the recent 23W poster session in March, Sofia Goncalves ’25 presented her work Mathematics in Magic: Looking into the Magic of Universal Cycles. Sofia’s mentor was fifth-year graduate student Alex Wilson, whose research focuses on algebraic combinatorics, specifically combinatorial representation theory. Photo by Lizzie Buchanan

Alex Lubotzky, Professor of Mathematics at the Einstein Institute of Mathematics and at the Weizmann Institute of Science, will give a lecture titled New directions in error correcting codes at 6 p.m. on Monday, April 17 in 008 Kemeny. Lubotzky holds the Maurice and Clara Weil Chair in Mathematics at Hebrew University and is a leading researcher in group theory, having solved a number of central problems in that field and its applications to combinatorics, geometry, and theoretical computer science. According to his talk’s abstract: “We will present some of the sources and highlights of [the mathematical theory of ECC], putting an emphasis on the 1990s breakthrough of Sipser and Spielman, who created low-density parity check (LDPC) codes, as well as the recent solution to the long-standing problem of the existence of locally testable codes (LTC). These codes, whose existence was doubted for many years, enable the receiver to check if the message is mostly correct by reading only a few bits of it, a property that seems very counterintuitive!” Interesting in learning more about Lubotzky's work?

Mathematics and Computer Science professor Peter Winkler has been elected a fellow of the American Association for the Advancement of Science, as reported in Dartmouth News. Professor Winkler is one of 505 scientists, engineers, and innovators spanning 24 scientific disciplines who are being recognized for scientific and socially notable achievements spanning their careers. AAAS recognized Winkler for contributions to combinatorics, discrete mathematics, and probability, and for his extraordinary work as an ambassador for mathematics. He has authored more than 150 research papers, with a primary focus on the intersection of probability theory, combinatorics, and theory of computing. “For me, the main motivating question for my research is, ‘Why is it that some things are easy to compute and others seem to be very hard?’ There are a lot of mysteries. I use mathematics to try to understand this phenomenon. It’s really fun to see something that you didn’t understand before.” In spring term 2023 he will be teaching Game Theory: Classical and Combinatorial, continuing his tradition of teaching a graduate probability course of interest to both computer scientists and mathematicians.

Congratulations to fifth-year PhD student Lizzie Buchanan, the recipient of this year’s Kenneth P. Bogart Teaching Award for dedication to and excellence in advancing the educational mission of the department! Buchanan, who this month received her Certificate in Mathematical Pedagogy, has taught Math 3 and Math 8, and will be teaching Math 22 in Spring ’23. Her research interests are in topology, specifically knot theory. In addition to teaching, she is also a mentor in the Winter Term 2023 Directed Reading Program, and for the past two years has supported our PhD students in her role as our department's Graduate Program Committee Liaison. “I am a huge fan of tactile and visual aids, and I try to incorporate them as much as possible,” Buchanan says. “For example, I bring in bowls, vases, and shoes to help visualize volumes of revolution or surfaces like paraboloids. I intentionally use common items instead of specially made math aids, because then my students can mentally attach a new unfamiliar object to a familiar one, making the new one easier to ‘hold’. Throwing around a travel pillow to talk about saddle points can be fun and silly, and makes the concept less intimidating.”

Congratulations to Professor Ina Petkova, one of six Dartmouth recipients of the National Science Foundation’s Faculty Early Career Development Program (CAREER) awards in 2022, as recently featured in Dartmouth News. “The CAREER grant is the NSF’s most prestigious award in support of early-career faculty. These awards are very difficult to obtain, particularly in pure mathematics,” says department chair Sergi Elizalde. Petkova studies the mathematics of knots, and with funding support from the CAREER grant, she will advance what are called cut-and-paste techniques of studying knots and links. As Principal Investigator, Petkova intends to further develop an invariant from bordered Floer homology for contact 3-manifolds with convex boundary, and use this invariant to address open questions in contact topology, an area with applications in physics, including classical mechanics, thermodynamics, and control theory. She also plans to extend bordered Floer homology and tangle Floer homology to integral coefficients and understand and develop the connections between knot Floer homology and quantum algebra.

“Why are we so intrigued by the infinite? Maybe it’s because of the tension between our finite lives and the seemingly unbounded range of our imagination,” writes Professor Dan Rockmore in his review of Netflix’s new documentary, A Trip to Infinity, in The New Yorker Annals of Inquiry. Rockmore is familiar with the fine balance needed when communicating mathematical concepts using film as a medium, having co-produced the 2002 NSF-funded educational documentary The Math Life, which featured lively interviews with a diverse group of mathematicians. “Math documentaries always pose a challenge to filmmakers because mathematics does not exist in the realm of images but in the realm of ideas,” says Rockmore, referencing his earlier Annals of Inquiry essay The Myth and Magic of Generating New Ideas.

What does a photo of Sister Mary Kenneth Keller teaching R. Buckminster Fuller about computer programming tell us about Dartmouth’s early computing history? Prior to being the first person in the U.S. to earn a PhD in Computer Science, Mary Kenneth Keller, a Catholic religious sister, participated in an NSF-funded summer program led by Mathematics Professor Tom Kurtz to introduce high school teachers to computing, using the College’s first computer, an LGP-30 (console on left) in 1961. She went on to receive her doctorate in Computer Science from the University of Wisconsin–Madison in June 1965 and became a widely known and respected pioneer in computing education. A recent pre-print about Mary Kenneth Keller notes it was her first experience in computer education: “It looked to me as if the computer would be the most revolutionary tool for doing math that I could get.” Just a few years later, Dartmouth reached the conclusion that “learning to use a high-speed computer should be an essential part of liberal education,” resulting in the creation of BASIC in 1964 under the leadership of Professors Kurtz and John Kemeny.

A recent article in Scientific American features the work of Professors Carolyn Gordon and David Webb in the field of spectral geometry, which provides information about geometric shapes based on their vibration frequencies. In 1992, Gordon, Webb, and Scott Wolpert, currently an emeritus professor at the University of Maryland, published a groundbreaking paper, One cannot hear the shape of a drum, in which they provided examples of differently shaped heads of drums that produce the same sound. The Scientific American article, Mathematicians Are Trying to ‘Hear’ Shapes—And Reach Higher Dimensions, goes on to describe more recent work in the field. Gordon and Webb present spectral geometry more generally in a 1996 article in American Scientist where they make an analogy between spectral geometry and spectroscopy which can be used to identify elements in distant stars by looking at the spectrum of the light they produce. The figure here, from their 1996 article, depicts two drumheads of different shapes having the same vibration frequencies.

In a wonderful and popular new Numberphile video, Jared Duker Lichtman AB, AM ’18 expounds and further discusses his recent proof of the Erdős primitive set conjecture. Lichtman talks in some depth about primes and primitive sets, describing his fascination with uncovering hidden mathematical beauty and structure within an ostensibly very chaotic class of sets. When he heard about this particular Erdős conjecture during his undergraduate years at Dartmouth, Lichtman states that he “absolutely fell in love with the problem, because it’s saying that these primes are very special in a precise way... I just found this such a beautiful statement.” In a second, follow-up Numberphile video, Lichtman provides additional context for primitive sets in general and mentions some examples of related open problems. He dedicates his proof of the Erdős primitive set conjecture to his undergraduate advisor, Professor Carl Pomerance, with whom he has written several joint papers.

In February Jared Duker Lichtman AB, AM ’18, currently a Clarendon Scholar at the University of Oxford Mathematical Institute, released A proof of the Erdős primitive set conjecture, resolving a longstanding conjecture which states that the Erdős sum of the set of prime numbers is the largest of any set of primitive numbers (sets in which no number divides any other). Lichtman began working on the primitive set conjecture with his advisor, Professor Carl Pomerance, while an undergraduate at Dartmouth. Their work led to several joint papers, including The Erdős conjecture for primitive sets and A generalization of primitive sets and a conjecture of Erdős. Quanta Magazine describes his resolution of the conjecture in some detail. You may read Lichtman’s own explanation of his fascination with this topic and watch a short video in an article by the Oxford Mathematical Institute. Noted number theorist András Sárközy, who co-authored many papers with Paul Erdös, said proof of the conjecture “seemed beyond reach”; other number theorists were of similar opinion. Please join us in congratulating our alumnus on this major achievement!

Could you tell if an online review describing the palate-pleasing notes of grapefruit and tangerine in your off-dry Riesling was written by a human, or by an algorithm? Professor Dan Rockmore is part of a team that developed software to produce original expert wine reviews and syntheses of beer reviews using existing datasets and product metadata. Both approaches use transformer-based deep learning neural net architecture. Started by former Neukom Institute fellow Allen Riddell, right, and developed under Rockmore’s guidance by Keith Carlson, Guarini ’21 and postdoctoral research fellow at Tuck, the project became a cross-campus collaboration resulting in a paper in the International Journal of Research in Marketing. Practical applications include tools to assist consumers and professional reviewers, although the paper acknowledges and explores the inherent ethical implications involved.

Byrne Scholar Maria Castro ’23, right, took on research last winter seeking to explore the ways in which the 1965 Immigration Act changed the scope of legal immigration into the US. Working with Economics professor Elizabeth Cascio, she compared countries that were impacted far more by the Act to countries largely unaffected by the new legislation. They found that after the Act, the share of unauthorized immigration grew in countries whose restrictions had expanded. “We tried to control for factors like civil wars, natural disasters, and economic disparities as we ran regressions to explore the relationship between unauthorized immigration and countries most affected by the Hart-Celler Act,” says Maria. “My research with Professor Cascio sought to contribute to economic immigration research, which remains largely unexplored.” Maria is an Economics major and LALACS minor interested in exploring research related to labor and public economics.

Congratulations to Melanie Fraser PhD ’19, Assistant Professor of Mathematics at Southern New Hampshire University, whose paper Lewis Carroll and the Red Hot Potato: A graph theoretic approach to a linear algebraic identity is featured on the 2022 Editor's Choice list in Discrete Mathematics! In 1866, Charles Dodgson, better known as Lewis Carroll, published an algorithm for computing the determinant of a matrix. Fraser created a new proof of the Lewis Carroll Identity and its equivalence to a graph-theoretic approach called the Forest Identity. The paper is will be freely accessible for the rest of the year, and replication code for the algorithm, coded in Mathematica, is publicly available. While earning her PhD in Mathematics under the supervision of Professor Peter Doyle, Fraser received Dartmouth’s 2019 Graduate Teaching Award. She also gave a talk about the research leading up to her paper at the “AMS Special Session on Advances by Early Career Women in Discrete Mathematics” at JMM 2019.

Graduate student Matt Jones, center, is lead author on the paper Polarization, abstention, and the median voter theorem, recently published in Humanities and Social Sciences Communications. With co-authors Feng Fu and Antonio Sirianni, Jones developed a mathematical model in response to apparent limitations in the median voter theorem, long considered the default model of voter behavior and candidate choice. Taking into consideration three contemporary factors — the influence of ideologically motivated third-party candidates, varied reasons for voter abstention, and increasing political polarization — the new model suggests voters may be drawn further to either side of a one-dimensional political spectrum, with the existence of extreme third-party candidates potentially causing a distributional tipping point with a feedback effect. “The minimal number of realistic assumptions necessary to obtain this result makes it all the more compelling and concerning,” state the authors, who propose continued reassessment of existing rational choice voting models.

In a touching memorial tribute appearing this month in Notices of the AMS, Professor Carl Pomerance and co-author Andrew Granville write on the remarkable life of mathematician Richard K. Guy, who passed away in 2020 at the age of 103. The article is a fascinating human interest story as well as an exploration into Guy’s mathematical research interests of combinatorial game theory, number theory, and geometry. For Guy, who initially considered himself an enthusiastic amateur mathematician, an encounter with Paul Erdős in 1960 was transformative: “He ended up writing four papers with Erdős, even solving an Erdős problem and developing his voracious appetite for unsolved problems.” For many years Guy ran a Research Problems column in the American Mathematical Monthly, and his books Unsolved Problems in Number Theory and The Book of Numbers (joint with John Conway) continue to inspire and delight both experienced and aspiring mathematicians.

Neukom Fellow Olivia Chu is co-author of the paper The microdynamics of spatial polarization: A model and an application to survey data from Ukraine, recently published in December’s special feature in PNAS. Chu is a Neukom Postdoctoral Fellow whose research focuses on the dynamics of human behavior and in particular, the effects that heterogeneous population structures have on these dynamics. Mentored by Professor Feng Fu, her research has applications to the evolution of cooperation, social integration, and polarization. In the paper, she and co-authors use a modified version of the adaptive voter model combined with survey data to show how social learning from other individuals in discussion networks can explain growing local consensus, while at the same time exacerbating spatial differences in attitudes. Chu recently presented her work in a virtual seminar at Santa Fe Institute's CounterBalance series on cyberhate, misinformation, social polarization, and other applied aspects of belief dynamics.

Professor Ina Petkova is a recipient of the National Science Foundation’s Faculty Early Career Development Program (CAREER) award, described as its “most prestigious award in support of early-career faculty who have the potential to serve as academic role models in research and education and to lead advances in the mission of their organizations.” The grant will provide funding over the next five years for her project, Bordered Floer homology and applications, and for mentoring and outreach. As Principal Investigator, Professor Petkova will seek to develop and apply cut-and-paste mathematical tools in low-dimensional topology. She intends to further develop an invariant from bordered Floer homology for contact 3-manifolds with convex boundary, and use this invariant to address open questions in contact topology, an area with applications in physics, including classical mechanics, thermodynamics, and control theory. She also plans to extend bordered Floer homology and tangle Floer homology to integral coefficients and understand and develop the connections between knot Floer homology and quantum algebra.

Congratulations to Zachary Couvillion ’22, the recipient of the 2022 John J. Byrne Jr. Prize in Mathematics! This prize was established in 2019 and is awarded to the top Dartmouth graduating mathematics major interested in continuing mathematics at the graduate level. “I would say that the algebra track at Dartmouth made a particularly strong impact on my future research interests,“ says Zach. “I studied specializations of Belyi maps with Professor Voight, and some aspects of the project are evolving toward a senior thesis. I hope to begin a PhD program in math in the Fall of 2022 and explore more topics in algebra and number theory. I have received excellent mentorship and support from the math department at Dartmouth, and I am excited to continue this journey in mathematics.”

Since 2019 Professor Peter Winkler has hosted a series of discussions on “Probability and Intuition” over dinner in New York City. The series, started by MoMath, often focuses on mathematical questions with surprising answers. Professor Dan Rockmore describes one of the gatherings in a recent article in The New Yorker. “You don’t need to be a researcher or math teacher to appreciate the beauty of mathematics, any more than you need to be a composer or performer to enjoy music,” says Winkler. Puzzles are his particular specialty. “Puzzles are my outreach device. I like to use puzzles to teach, to get people excited, and to challenge them to think.” One recent guest reported struggling with a certain puzzle: “On average, how many cards does it take to get to a jack in a shuffled deck of fifty-two cards?” (A good exercise for our readers!) You can register to receive a new puzzle every week from Professor Winkler at mindbenders.momath.org.

In the January 13, 2022 issue of The New York Review of Books [may require subscription], Professor Dan Rockmore gives a delightfully erudite review of Philip Ording’s 99 Variations on a Proof. Ording’s book was inspired by Raymond Queneau’s Exercises in Style (1947) and is wide in scope and style — deep, historical, amusing, and playful — as is Professor Rockmore’s review. “Mathematics is writing,” says Rockmore. A proof is “as close to the written transmission of one person’s pure thought as any writing can be. But even in mathematical writing, it’s not just what you say but how you say it — better known as style.” Rockmore, Professor of Mathematics and director of the Neukom Institute, is co-editor of the recently published book Law as Data: Computation, Text, & the Future of Legal Analysis.

Byrne Scholar and Mathematical Data Science major Joe Gyorda ’22, second from left, interned this summer at HALE Sports, which seeks to optimize the health and performance of athletes through analyzing somatic and biometric data. “The first team was building a computer vision model in which athletes could receive real-time feedback on various exercises (e.g., squat, pushup) to correct their form. Machine learning and body pose estimation models were implemented to analyze body position/angles and identify correct/incorrect form,” says Joe, himself a triathlete. In his second team Joe worked with longitudinal somatic survey data collected from college athletes, with the goal being to implement clustering algorithms to track athlete variables over time and using predictive models to determine which variables (e.g., energy, mood) are impacted by changes in another (e.g., sleep). “I am very grateful for the generosity of the Byrne Fund for supporting me and my work!”

The department welcomes Assistant Professor Ethan Levien, whose research interests include stochastic processes, mathematical biology, and applied statistics. Professor Levien, who will be starting his own research group in our department, obtained his PhD in Mathematics from the University of Utah, where he studied the stochastic dynamics of chemical reaction networks. He went on to spend three years as a postdoctoral fellow in applied mathematics at Harvard University and Brandies University. His current research focuses on the role of randomness in biology, especially single-cell physiology and evolution. “Using mathematics, I try to answer questions such as: How do cells regulate their size? Why do certain traits appear to evolve separately in distinct organisms? What causes physiological differences in genetically identical cells?”

Cristopher Moore, Professor at the Santa Fe Institute, will give a lecture titled Easy, Hard, and Impossible: The Limits of Computation at 6 p.m. on Wednesday, October 6 in 008 Kemeny Hall. From the abstract: “Every day we ask computers to solve problems for us — to find the fastest route across town, fold a protein into the right shape, or prove an unsolved mathematical question. In each case the space of possible solutions is vast. Why is it that for some problems, we can quickly zoom in on the solution, while for others it’s like looking for a needle in a haystack? What is it about the structure of a problem that makes it easy, or hard, or even impossible to solve?” (Click/tap to view a larger image.)

The Fields Medal is awarded to only a few young mathematicians every four years and was, in part, intended to recognize underrepresented mathematicians. In their analysis Elitism in mathematics and inequality, published in Humanities and Social Sciences Communications and referenced in Scientific American, former Byrne Scholar Ho-Chun Herbert Chang ’18 and Professor Feng Fu explore how 60 Fields Medal recipients relate to each other and to the broader community of mathematicians. They find that while the medal has helped to promote some previously underrepresented groups, a “Western bias” is still evident, along with an under-representation of minority groups. In particular, the study found that 44 out of 60 Fields medalists come from a highly interconnected group of mathematicians. Image by Shirley Wu.

In July SIAM News highlighted research by second-year graduate student Alina Glaubitz (joint with Professor Feng Fu) and her work on the oscillatory dynamics of social distancing. In her presentation, delivered virtually at the 2021 SIAM Annual Meeting, Alina described how she and Professor Fu incorporated an evolutionary game theory model into the epidemiological process, revealing the presence of a feedback loop between infections and social distancing. This feedback loop, an “oscillatory tragedy of the commons,” can lead to multiple waves of infection in emerging novel zoonotic diseases, such as COVID-19, which are caused by respiratory viruses and are highly contagious through proximity transmissions.

Professor Carl Pomerance was an invited speaker to a recent conference of the Northeastern Section of the MAA. His talk, ‘Is 73 the best number?’, was connected to his paper Proof of the Sheldon Conjecture (co-authored with Chris Spicer), which proved a mathematical concept inspired by an episode in the CBS series The Big Bang Theory. As stated in his talk’s abstract, “According to Sheldon Cooper, the often annoying lead character in the TV sitcom The Big Bang Theory, 73 is the best number. And he's eager to tell you why. But is it really? In joint work with Chris Spicer (Morningside College in Iowa), we show Sheldon just may be right.” Sheldon photo credit: Michael Yarish/©2019 Warner Bros. Entertainment Inc.

On Father’s Day, The New Yorker published a reflective essay by Professor Dan Rockmore discussing the history of mathematical proofs and the major influence of one particular proof — the Rockmore theorem, developed by his father — on his own family’s history. About his father, a professor emeritus in the theoretical nuclear physics group at Rutgers, Rockmore says “My dad still marvels at a career and a life that he never could have anticipated... math was a gateway to order in his life.” Reflecting on the equations in his father’s proof brings Proustian moments: “For me, the symbols are mathematical madeleines. They remind me of the pads of paper that were scattered around our house, each full of my father’s scribblings.”

“The 2020-2021 school year (junior year for the Class of 2022) wasn’t exactly how anybody could have predicted when my class matriculated,” says Byrne Scholar Maria Roodnitsky ’22. However, thanks to the generous Byrne gift, Maria had the opportunity to spend an off term as a software engineering intern working on improving accessibility features in an iOS application with the mobile development team at Grove Collaborative. “I never could have imagined three years ago that I would be applying my love for data science and mathematics in the technology sector,” says Maria. “Having used funding to do both hands-on research with a renowned statistician and to go work in the industry itself, I can safely say that as a result of the Jack Byrne Scholars Program, I am one step closer to knowing what I want to do post-graduation. I look forward to seeing what else is in store!”

Professor Feng Fu was the senior researcher on a study of political discourse in social media published in Physical Review X. In the article Public Discourse and Social Network Echo Chambers Driven by Socio-Cognitive Biases, Professor Fu, visiting scholar Xin Wang, and their co-authors present a computational model demonstrating how aggressive political messages conveyed through social media can lead to polarization and the formation of echo chambers. “This research finds that overly-amplified exposure and super-strong positioning of a campaign can actually lessen the likelihood of winning the widespread support that is desired,” says Professor Fu. “Political strategists need to consider how attack ads and other extreme messages might backfire,” observes Xin Wang, lead author of the paper.

In The New Yorker Annals of Inquiry, Professor Dan Rockmore reflects on the lives of three mathematicians we lost in 2020: John Conway, Ronald Graham, and Freeman Dyson. These three were among those interviewed by Professor Rockmore and his co-producers in their 2002 documentary The Math Life. In his New Yorker essay, Professor Rockmore explores not only their contributions, but also the human dimension of mathematics, touching on the joy of embarking on journeys of discovery. As John Conway stated, “I can sit here in this chair and go on a voyage of exploration. A very different voyage of exploration, but, still, there are things to be discovered, things to be seen, that you can quite easily be the first person ever to see.”

A recent Quanta article mentions several Dartmouth connections in the quest to solve one of number theory’s most intriguing puzzles: are there any odd perfect numbers (OPNs)? Professor Carl Pomerance proved one of the many necessary conditions for OPNs as part of his thesis work, and in 1999 Professor John Voight, inspired by Richard Guy’s book Unsolved Problems in Number Theory, discovered a new kind of spoof OPN. Graduate student Grant Molnar was involved in subsequent work by the BYU Computational Number Theory Group, whose research led to the discovery of some interesting properties of spoofs. Paul Pollack, PhD ’08, professor of mathematics at UGA, expresses caution as to whether these properties may lead to a proof of the non-existence of OPNs, while Professor Voight says “It is indeed a problem for the ages, [and] perhaps it will remain so.”

Quaternion Algebras by Professor John Voight will soon be published in hardcover and e-book form. Part of Springer’s Graduate Texts in Mathematics series, and opening with a description of what is possibly the “most famous act of mathematical vandalism” in history, the over 800-page monograph encompasses a vast wealth of knowledge at the intersection of many fields, according to Springer. As Professor Voight writes in the book’s preface, “It is somehow fitting that I would find myself writing this text while a faculty member at Dartmouth College: the story of the quaternions is interwoven with the history of mathematics at Dartmouth.” View the current version on Professor Voight’s Quaternions page.

Manifolds provide mathematicians and other scientists with a way of grappling with the concept of “space” (from a global viewpoint). The space occupied by an object. The space that we inhabit. The space of solutions to a system of equations. Or, perhaps, the space of configurations of a mechanical system. While manifolds are central to the study of geometry and topology, they also provide an appropriate framework in which to explore aspects of mathematical physics, dynamics, control theory, medical imaging, and robotics, to name just a few. This course will demonstrate how ideas from calculus can be generalized to manifolds, providing a new perspective and toolkit with which to explore problems where “space” plays a fundamental role.
