Suppose f is a function with Fourier transform supported on the
unit sphere in Rd. Elias Stein conjectured in the 1960s that the Lp
norm of f is bounded by the Lp norm of its Fourier transform, for
any p>2d/(d−1). We propose to study this...
Let Y be a symplectic divisor of X, ω. In the Kahler setting,
Givental's Quantum Lefschetz formula relates certain Gromov-Witten
invariants (encoded by the G function) of X and Y. Given an
Lagrangian L in (Y, ω|Y), we can lift it to a Lagrangian L'...
In this talk, we present a new method to solve algorithmic and
combinatorial problems by (1) reducing them to bounding the
maximum, over x in {-1, 1}^n, of homogeneous degree-q multilinear
polynomials, and then (2) bounding the maximum value...
Correlation functions of the average null energy operator
provide direct theoretical models of collider experiments, and have
played a crucial role in contemporary developments in formal QFT
and gravity. Recently it has become possible to directly...
I will explain how to realize a gapped Hamiltonian for a (1+1)d
system on the lattice which has a categorical symmetry given by the
modules of the 4-dimensional Taft algebra. This category is finite
but not a fusion category, a fact that presents...
In the late 1800s, in the course of his study of classical
problems of number theory, the young Hermann Minkowski discovered
the importance of a new kind of geometric object that we now call a
convex set. He soon developed a rich theory for...
The satisfiability problem for Constraint Satisfaction Problems
(CSPs) asks whether an instance of a CSP has a fully satisfying
assignment, i.e., an assignment that satisfies all constraints.
This problem is known to be in class P or is NP-complete...
We explore the construction of non-Weinstein Liouville geometric
objects based on Anosov 3-flows, introduced by Mitsumatsu, in the
generalized framework of Liouville Interpolation Systems and
non-singular partially hyperbolic flows. We discuss the...
Equivariant cohomology was introduced in the 1960s by Borel, and
has been studied by many mathematicians since that time. The
talks will be an introduction to some of this work. We will
focus on torus-equivariant cohomology (as well as
Borel-Moore...
The reverse Khovanskii-Teissier inequality is a three term
inequality for nef divisors which first appeared in the context of
Kähler geometry. It provides an upper bound on a product of two
divisors in terms of products with the third, hence its...
