The physicist Abrikosov predicted that in certain
superconductors, one should observe triangular lattices of
vortices, now called Abrikosov lattices. When studying ground
states of Coulomb gases, which is motivated by questions in
approximation...
In this talk, I will give an overview of some recent results
motivated by the computation and applications of persistent
homology, a theory that creates a bridge between the continuous
world of topology and the discrete world of data, and
assigns...
The group of Hamiltonian diffeomorphisms of a symplectic
manifold admits a remarkable bi-invariant metric, called Hofer’s
metric. My talk will be about a recent joint work with Dan
Cristofaro-Gardiner and Vincent Humilière resolving the
following...
Art critic and historian, Hal Foster, will discuss how artists
created an aesthetic of “positive barbarism” in a world devastated
by World War II, the Holocaust, and the atomic bomb.
Consider the function field F of a smooth curve over FqFq,
with q>2q>2.
L-functions of automorphic representations
of GL(2)GL(2) over FF are important objects for
studying the arithmetic properties of the field FF.
Unfortunately, they can be...
The anti-spherical modules over the affine Hecke algebras admit
two different realizations: one realization is in terms of the
space of Whittaker functions on the affine flag manifolds and the
other realization, due to Kazhdan-Lusztig, is in terms...
A discrete countable group is matricially stable if its finite
dimensional approximate unitary representations are perturbable to
genuine representations in the point-norm topology. We aim to
explain in accessible terms why matricial stability for a...
This talk introduces a directed analog of the
classical Laplacian matrix and discusses algorithms for
solving certain problems related to them. Of particular interest is
that using such algorithms, one can compute the stationary
distribution of a...
I will survey results related to graph comparison; graph
comparison is a certain type of restriction on a metric spaces
which is encoded by a given graph.
