SUMMARY:Carolyn Gordon: Decoding geometry and topology from the
Steklov spectrum of orbisurfaces
DESCRIPTION:The Dirichlet-to-Neumann operator of a surface $M$ with
boundary or higher-dimensional analogue is a linear map
$C^\\infty(\\partial M)\\to C^\\infty(\\partial M)$ that maps the
Dirichlet boundary values of each harmonic function f on M to the
Neumann boundary values of f. The spectrum of this operator is
discrete and is called the Steklov spectrum. The
Dirichlet-to-Neumann operator also generalizes to the setting of
orbifolds\, e.g.\, cones. We will address the extent to which the
Steklov spectrum encodes the geometry and topology of the surface or
orbifold and\, in particular\, whether it recognizes the presence of
orbifold singularities.\n

SUMMARY:Daniel Ruberman: Configurations of embedded spheres
DESCRIPTION:A venerable problem in combinatorics and geometry asks
whether a given incidence relation may be realized by a
configuration of points and lines. The classic version of this would
ask for lines in a projective plane over a field. An important
variation allows for {\\em pseudolines}: embedded circles (isotopic
to ${\\mathbb R}P^1$) in the real projective plane. I will describe
joint work with Laura Starkston about a `complexified' version of
the problem. This is the question of when a configuration is
realized by a collection of complex lines (each homeomorphic to
${\\mathbb C}P^1$\, i.e. a $2$-sphere) embedded\, in a topological
or smooth fashion\, in the complex projective plane.

SUMMARY:Daniel Forger: Novel mathematical tools for understanding
human behavior with applications to jetlag and shiftwork
DESCRIPTION:15 million US workers follow night or nonstandard
shifts. A similar number of Americans travel overseas each year.
This leads to misalignment of the daily (circadian) clock in
individuals: a clock that controls sleep\, performance\, and nearly
every physiological process in our body. Consequences include many
of the reported major industrial accidents and automobile deaths. In
the first half of this talk\, I demonstrate how\, when using a
“simple” ode mathematical model of this clock\, one can optimize
schedules for transmerdian travelers and shiftworkers to maximize
productivity and minimize jetlag. I then show how our smartphone
app\, ENTRAIN (www.entrain.org)\, which has been downloaded nearly
200\,000 times in over 100 countries\, simulates models and employs
these optimized schedules. In the second half\, I describe how
large-scale mathematical models of brain regions controlling
circadian timekeeping push the limits of scientific computing.
Using a population density/particle method\, contraction to low
dimensional manifolds\, and a new anzatz for simplifying coupled
oscillator problems\, I show how one can relate these simulations to
predictions of jet lag and productivity. This work also presents a
new paradigm for how one studies human behavior\, where large-scale
computing and mathematical analysis can translate basic
neuroscience\, to yield hypotheses that can be rapidly tested
against social factors using mobile and wearable technology.

SUMMARY:Mike Wong: Unoriented skein relations for grid homology and

DESCRIPTION:Although the Alexander polynomial does not satisfy an
unoriented skein relation\, Manolescu (2007) showed that there
exists a skein exact triangle for knot Floer homology. In this
talk\, we will give a combinatorial proof of this result using grid
homology. If time permits\, we will outline a similar skein relation
for the Petkova-Vertesi tangle Floer homology (joint work with Ina
Petkova).

SUMMARY:Jonathan Bloom: Rook and Wilf equivalence in integer
partitions
DESCRIPTION:The subjects of rook equivalence and Wilf equivalence
have both attracted considerable attention over the last
half-century. We will start with a review of Rook Theory\, i.e.\,
the study of the number of configurations of $k$-rooks on a broken
chess board\, as established by Kaplansky and Riordon in the 1940's
and later characterized by Foata and Shutzenberger in the 1970's.
We then introduce a new notion of Wilf equivalence for integer
partitions and also discuss a characterization of the related
generating function. This alternate characterization allows us to
prove that rook equivalence implies Wilf equivalence. We are also
able to prove that if we refine the notions of rook and Wilf
equivalence in a natural way\, then these two relations coincide.

SUMMARY:W. S. Don: High Order Hybrid Compact-WENO Finite Difference
Schemes for Hyperbolic Conservation Laws
DESCRIPTION:Ever since the development of the high order WENO finite
difference scheme by Jiang and Shu\, it has been widely adopted for
solving hyperbolic conservation laws that captures shocks
essentially non-oscillatory while resolving fine scale structures
efficiently. Numerous advances have been proposed to reduce the
dissipation and dispersion errors by improving/modifying certain
critical components of the WENO reconstruction procedure\, such as\,
the definitions of nonlinear weights and the smoothness indicators
and the tuning of existing parameters. Despite the enhancement of
the scheme\, hybrid scheme that conjugates the high order linear
compact and nonlinear WENO FD scheme can be employed to improve the
performance of the scheme in the smooth regions of the solution. I
will briefly introduce several key components and enhancements to
improve the robustness of the high order shock detection algorithms
based on\, the high order multi-resolution analysis\, conjugate
Fourier analysis\, and Radial basis function. Classical examples in
shallow water equation with shock-like hydraulic jumps based on the
well-balanced hybrid schemes and Euler equations for compressible
gas dynamics and detonation wave simulations based on the bound
preserving hybrid schemes will be presented to demonstrate the
performance of the hybrid schemes in terms of resolution power\,
dissipation\, and efficiency.

SUMMARY:Sara Maloni: Combinatorial methods on actions on character
varieties.
DESCRIPTION:Abstract: In this talk we consider the
SL(2\,C)-character variety of the four-holed sphere S\, and the
natural action of the mapping class group MCG(S) on it. In
particular\, we describe a domain of discontinuity for the action of
MCG(S) on the relative character variety\, which is the set of
representations for which the traces of the boundary curves are
fixed. I will focus on the combinatorial view point we adopt using
trace functions on simple closed curves. \nTime permitting\, in the
case of real characters\, we show that this domain of discontinuity
may be non-empty on the components where the relative Euler class is
non-maximal. We might also discuss similar results for the
three-holed projective plane (and see how these two cases are sort
of "dual").\n(This is joint work with F. Palesi and S. P. Tan.)

SUMMARY:Michael Pevzner: Rankin-Cohen brackets\, symmetry breaking
operators and the F-method
DESCRIPTION:Symmetry breaking operators appear in various areas of
Mathematics and Theoretical Physics.\nAfter a short panorama of
classical examples we will discuss the link between the celebrated
Rankin-Cohen brackets and fusion rules for holomorphic discrete
series representations of the Lie group SL(2\,R). This remark will
lead us to an intrinsic explanation of the fact that Rankin-Cohen
brackets can be expressed in terms of Jacobi polynomials. This
approach relies on a new method of analysis of intertwining
operators that we shall illustrate by several examples.

SUMMARY:Arseniy Sheydvasser: Quaternion Algebras and Sphere Packings
DESCRIPTION:We call an n-sphere packing an integral Gamma-packing if
it is the limit set of some thin\, geometrically finite Kleinian
group\, and the curvatures of all the spheres are integers. The
classic example is the Apollonian gasket. There are many known
examples of integral Gamma-packings for n = 1\, but even the n = 2
case is largely uncharted territory. In this talk\, we will discuss
a method of constructing integral Gamma-packings from orders of
quaternion algebras closed under involution.

SUMMARY:Craig Sutton: Detecting the Moments of Inertia of a Molecule
via its Rotational Spectrum
DESCRIPTION:Abstract: Spectral geometry has connections with the
field of spectroscopy where one is interested in recovering the
structure and composition of a molecule or compound from various
spectral data. We demonstrate that the moments of inertia of a
molecule can be recovered from its rotational spectrum.
Geometrically speaking this means that the isometry classes of
left-invariant metrics on $\\operatorname{SO}(3)$ can be mutually
distinguished via their spectra. In fact\, they can be distinguished
by their first four heat invariants. More generally\, we demonstrate
that among compact homogeneous three-manifolds a non-trivial
isospectral pair must consist of spherical three-manifolds
possessing non-isomorphic cyclic fundamental groups and each is
equipped with a so-called Type I metric: at present\, no such
isospectral pairs exist in the literature. This is joint work with
Ben Schmidt (Michigan State University).

SUMMARY:John Voight: Fake quadrics
DESCRIPTION:A fake quadric is a smooth projective surface that has
the same rational cohomology as a smooth quadric surface but is not
biholomorphic to one. We complete the classification of fake
quadrics uniformized by the product of upper half planes according
to the commensurability class of their fundamental group. To
accomplish this task\, we develop a number of new techniques that
explicitly bound the arithmetic invariants of a fake quadric and
more generally of an arithmetic manifold of bounded volume arising
from a form of $\\mathrm{SL}_2$ over a number field. This is joint
work with Benjamin Linowitz and Matthew Stover.

SUMMARY:Rosa Orellana: Symmetric group characters as symmetric
functions
DESCRIPTION: A very difficult problem in algebraic combinatorics is
to figure out a combinatorial rule for computing the Kronecker
coefficients. The Kronecker coefficients are obtained when we
tensor irreducible representations of the symmetric group. The
problem of combinatorially computing the coefficients when we tensor
representations of the general linear group is well-known. The
characters of the general linear group are obtained by evaluating
symmetric functions at the eigenvalues of matrices. And tensoring
representations corresponds to multiplying symmetric functions.
\n\nIn this talk I will introduce a new basis for symmetric
functions such that when evaluated at the eigenvalues of a
permutation matrix we get the irreducible characters of the
symmetric group. This basis has as structure coefficients the
stable (reduced) Kronecker coefficients. The introduction of this
new basis has introduced new combinatorial objects that will help in
finding a combinatorial rule for the Kronecker coefficients.
\n\nThis is joint work with Mike Zabrocki.

SUMMARY:Gestur \\'Olafsson: Reflection Positivity: Representation
Theory meets Quantum Field Theory
DESCRIPTION:Reflection positivity\, or Osterwalder-Schrader
quantization\, has its origin in the work of Osterwalder and
Schrader around 1973/1975 on constructive\nquantum field theory.
Their goal was to build a bridge from euclidean quantum theory to
relativistic quantum field theory by analytical continuation to
imaginary time.\n\n\nInterpreting the physical system as a unitary
(or anti-unitary) representation of the\ncorresponding symmetry
group this can be seen as transforming a representation from one Lie
group to a unitary/anti-unitary representation of\na dual Lie
group\, e.g. from the euclidean motion group to the Poincar\\'e
group. \n\nIn this talk we discuss resent developments\, starting
with the basic concept of reflection positive\nHilbert spaces and
reflection positive one-parameter groups and some examples of
reflection positive\nrepresentations. We will use simple examples
like the circle or the unite sphere $\\mathrm S^n$ in $\\mathrm
R^{n+1}$.

SUMMARY:Feng Fu: Dueling Biological and Social Contagions
DESCRIPTION:In this talk\, I will introduce voluntary vaccination
behavior\, a special form of human cooperation but central to public
health interventions. In particular\, I will discuss imitation
behavior of vaccination in social networks and its impact on
determining health outcomes. I will then present my most recent work
on analyzing the concurrent spreading of vaccination behavior and
seasonal influenza in an empirically observed social network.
Integrating real data with behavior-disease models\, this work\, and
the technical approach it introduces\, unravels the role that social
factors play in epidemiology and has practical implications for
improving disease control efforts. The methodology has broad
applicability to many other disparate\, competitive spreading
phenomena in social networks. Finally I will discuss applications of
these behavior-disease models to other contexts\, such as
understanding the tragedy of the commons in overuse of antibiotics.
This talk is based on joint work with Xingru Chen\, James H. Fowler
and Nicholas A. Christakis.
