Special Mathematical Physics Seminar

Loop Calculus in Statistical Physics and Information Theory
Misha Chertkov
2:00pm|S-101

Loop calculus is a new theoretical tool which allows to express partition function of a statistical inference/physics problem on a graph in terms of a series. Each term of the series is associated with a loop on the graph. Utility of the loop...

Fundamental Lemma

On the Fundamental Lemma for Weighted Orbital Integrals
10:30am|S-101

The first half of this talk will be devoted to describing Arthur's variant of the fundamental lemma for weighted orbital integrals. The second half will discuss a proof of the weighted fundamental lemma for Sp(4).

Number Theory Seminar

Discrete Transitive Actions on the Vertices of Bruhat-Tits Buildings
4:30pm|Princeton University, Fine Hall 214

In this work, joint with A. Mohammadi, we try to classify all the discrete transitive actions on the vertices of a Bruhat-Tits Building over a local field of characteristic zero. There are lots of such actions in the case of Bruhat-Tits tree, i.e...

Birational Geometry

Finite Generation One
Micea Mustata
1:00pm|S-101

This will be an informal working seminar, trying to understand the recent paper of Birkar, Cascini, Hacon and McKernan on the finite generation of canonical rings.

Complex Algebraic Geometry

Filtrations in Cohomlogy and Geometry
1:00pm|S-101

On a topological space, algebraic topology and homological algebra endow cohomology groups with various filtrations. In the case of algebraic varieties, one may wonder if such filtrations, e.g. the Grothendieck filtration, the Leray filtration, the...

Members’ Seminar

Open Gromov-Witten Theory of the Quintic Threefold
4:00pm|S-101

Recently, I defined an open Gromov-Witten invariant for Lagrangian submanifolds that arise as the real points of a real symplectic manifold. In this talk, I will discuss a calculation of the genus zero open Gromov-Witten theory of the Fermat type...

Fundamental Lemma

On Geometric Stabilization
10:30am|S-101

I will formulate the geometric interpretation of the stabilization of (a part) of the geometric side of the trace formula for Lie algebra. The SL(2) case will be discussed in some details.
