Professor Giannakis’ research highlighted in the Concord Monitor

November 03, 2021

Professor Dimitris Giannakis, whose research connects ideas from data science, machine learning, and dynamical systems theory, was recently quoted in an article in the Concord Monitor [may require subscription], speaking on the development of mathematical frameworks to improve understanding of complex systems such as the earth’s climate dynamics. “We are combining this existing body of theoretical knowledge from abstract math with data science ... to identify phenomena in nature and generate questions that are relevant at the abstract mathematical level as well as the world,” he says. “It brings in a lot of different fields of mathematics in one arena.” This image is from his paper Bridging Data Science and Dynamical Systems Theory (co-authored with Tyrus Berry and John Harlim), which was featured in the October 2020 issue of Notices of the American Mathematical Society. “I think mathematics is very beautiful as a language; beautiful in its own right, without reference to anything else,” says Professor Giannakis, who is a member of the Jack Byrne Academic Cluster in Mathematics and Decision Science.

Christopher Moore to give Reese T. Prosser Memorial Lecture

September 30, 2021

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.)

Herbert Chang ’18 and Professor Fu publish study on mathematical elitism

September 20, 2021

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.

Research by Alina Glaubitz featured in SIAM News

September 09, 2021

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 Pomerance asks ‘Is 73 the best number?’

September 08, 2021

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.

Professor Rockmore writes in The New Yorker

June 25, 2021

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.”

Research on the emergence of polarized echo chambers published in Physical Review X

March 23, 2021

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.

Professor Rockmore on three mathematicians we lost in 2020

January 20, 2021

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.”

Quanta article on the odd perfect number problem

October 08, 2020

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.”

Recent progress on a conjecture of Erdős

September 02, 2020

Jared Duker Lichtman AB, AM ’18, currently a Clarendon Scholar at the University of Oxford Mathematical Institute, describes recent progress on the Erdős primitive set conjecture. Lichtman’s work with Dartmouth Professor Carl Pomerance has led to several joint papers, including The Erdős conjecture for primitive sets and the forthcoming A generalization of primitive sets and a conjecture of Erdős. “I find it irresistible how subtle patterns emerge from basic multiplication,”says Lichtman. “The full Erdős conjecture has remained elusive, but working towards it has led to interesting developments.” Photo by Oxford Mathematical Institute

New course Math 72 (Honors Section): Calculus on Manifolds

August 23, 2020

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.
