Members’ Seminar

Gelfand Pairs and Invariant Distributions
2:00pm|S-101

First I will introduce the notion of Gelfand pair and its connection to invariant functions and distributions on the group, and give some examples. We will start from finite groups and compact groups and then go on to reductive groups over local...

Members’ Seminar

Pseudoholomorphic Curves and Dynamics in Dimension Three
2:00pm|S-101

The talk describes how pseudoholomorphic curve based techniques can be used to understand better the dynamics of autonomous Hamiltonian systems of two degrees of freedom restricted to a compact non-degenerate energy surface.

$A^1$-Homotopy Theory and Its Recent Developments

12:00am

There was a small program during the second term (spring) of the 2009-2010 year on $A^1$-Homotopy Theory and its recent developments. Two directions were emphasized during this program: the proof of Bloch-Kato conjecture on Galois cohomology and...

An Algorithmic Proof of Forster's Lower Bound
Moritz Hardt
10:30am|S-101

We give an algorithmic proof of Forster's Theorem, a fundamental result in communication complexity. Our proof is based on a geometric notion we call radial isotropic position which is related to the well-known isotropic position of a set of vectors...
