Analyticity results for the Navier-Stokes Equations

Guher Camliyurt
Member, School of Mathematics
January 31, 2019
We consider the Navier–Stokes equations posed on the half space, with Dirichlet boundary conditions. We give a direct energy based proof for the instantaneous space-time analyticity and Gevrey class regularity of the solutions, uniformly up to the boundary of the half space. We then discuss the adaptation of the same method for bounded domains.

Upper bounds for constant slope p-adic families of modular forms

John Bergdall
Bryn Mawr College
January 31, 2019
This talk is concerned with the radius of convergence of p-adic families of modular forms --- q-series over a p-adic disc whose specialization to certain integer points is the q-expansion of a classical Hecke eigenform of level p. Numerical experiments by Gouvêa and Mazur in the nineties predicted the general existence of such families but also suggested, in spirit, the radius of convergence in terms of an initial member. Buzzard and Calegari showed, ten years later, that the Gouvêa--Mazur prediction was false. It has since remained open question how to salvage it.

Minmax minimal surfaces in arbitrary codimension with

Tristan Rivière
ETH Zürich; Member, School of Mathematics
January 29, 2019

We shall present a procedure which to any admissible family
of immersions
of surfaces into an arbitrary closed riemannian manifolds assigns a
smooth, possibly branched, minimal surface
whose area is equal to the width of the corresponding minmax and whose
Morse index is bounded by the
dimension of the familly. We will discuss the question of bounding the
Morse index + Nullity from below as well as possible extensions of
this procedure to more general families.

PCP and Delegating Computation: A Love Story.

Yael Tauman Kalai
Microsoft Research
January 28, 2019

In this talk, I will give an overview on how PCPs, combined with cryptographic tools,
are used to generate succinct and efficiently verifiable proofs for the correctness of computations.
I will focus on constructing (computationally sound) *succinct* proofs that are *non-interactive*
(assuming the existence of public parameters) and are *publicly verifiable*.
In particular, I will focus on a recent result with Omer Paneth and Lisa Yang,
where we show how to construct such proofs for all polynomial time computations,

New Results on Projections

Guy Moshkovitz
Member, School of Mathematics
January 22, 2019

What is the largest number of projections onto k coordinates guaranteed in every family of m binary vectors of length n? This fundamental question is intimately connected to important topics and results in combinatorics and computer science (Turan number, Sauer-Shelah Lemma, Kahn-Kalai-Linial Theorem, and more), and is wide open for most settings of the parameters. We essentially settle the question for linear k and sub-exponential m.
