Non-Spectral Poles in Asymptotically Hyperbolic Scattering
Robin Graham
This talk will discuss non-spectral poles of the scattering
operator arising in problems with regular singular point behavior
at infinity. The phenomenon will be exhibited in a one-dimensional
model example involving the Yukawa potential on a half...
Potential Automorphy for Certain Galois Representations to GL(n)
Thomas Barnet-Lamb
I will describe recent generalizations of mine to a theorem of
Harris, Shepherd-Barron, and Taylor, showing that have certain
Galois representations become automorphic after one makes a
suitably large totally-real extension to the base field. The...
Curvature and Regularity of Optimal Transport
Curvature and Regularity of Optimal Transport
In 2005 Ma, Trudinger and Wang introduced a fourth-order
differential condition which comes close to be necessary and
sufficient for the smoothness of solutions to optimal transport
problems with a given cost function. If the cost function is
the...
Generalizations to Boltzmann-Maxwell Interaction Dynamics
We shall revisit the Boltzmann equation for rarefied non-linear
particle dynamics, of conservative or dissipative nature, and on
the stochastic N-particle model, introduced by M. Kac [19]. Related
to this equation, we consider a a probabilistic...
Characterizations of Sobolev Spaces and Related Inequalities
In this talk, I will discuss some characterizations of Sobolev
spaces, BV spaces, and present some new inequalities in this
context. As a consequence, I can improve classical properties of
Sobolev spaces such as Sobolev inequality, Poincare...
On a Conjcture of J. Serrin
Haim Brezis
In 1964 J. Serrin proposed the following conjecture. Let u be a
weak solution (in W^{1,1}) of a second order elliptic equation in
divergence form, with Holder continuous coefficients, then u is a
"classical" solution ( i.e. u belongs to H^1). I will...
Algorithmic Versions of Dense Model Theorems
Green and Tao used the existence of a dense subset
indistinguishable from the primes under certain tests from a
certain class to prove the existence of arbitrarily long prime
arithmetic progressions. Tao and Ziegler showed some general
conditions...
Approximating Submodular Functions Everywhere
Nick Harvey
Submodular functions are a key concept in combinatorial
optimization. Algorithms that involve submodular functions usually
assume that they are given by a (value) oracle. Many interesting
problems involving submodular functions can be solved using...
