Mathematical Conversations

Bourgain and the sum-product phenomena
6:00pm|Dilworth Room

In 2004 Jean Bourgain proved, with Netz Katz and Terry Tao, the "sum-product theorem in finite fields". He referred to this result (and proof technique) as a "goose which lays golden eggs". Indeed, in subsequent years, he has published a couple of...

The Eigencurve at Eisenstein weight one points
Alice Pozzi
4:30pm|West Building Lecture Hall

In 1973, Serre observed that the Hecke eigenvalues of Eisenstein series can be p-adically interpolated. In other words, Eisenstein series can be viewed as specializations of a p-adic family parametrized by the weight. The notion of p-adic variations...

Variational Methods in Geometry Seminar

(Non)uniqueness questions in mean curvature flow
3:30pm|Simonyi Hall 101

Mean curvature flow is the negative gradient flow of the volume functional which decreases the volume of (hyper)surfaces in the steepest way. Starting from any closed surface, the flow exists uniquely for a short period of time, but always develops...

Symplectic methods for sharp systolic inequalities
Umberto Hryniewicz
1:00pm|Simonyi Hall 101

In this talk I would like to explain how methods from symplectic geometry can be used to obtain sharp systolic inequalities. I will focus on two applications. The first is the proof of a conjecture due to Babenko-Balacheff on the local systolic...

Computer Science/Discrete Mathematics Seminar II

New Results on Projections
10:30am|Simonyi Hall 101

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...
