Joint IAS/Princeton University Number Theory Seminar

Nonabelian Cohen-Lenstra heuristics and function field theorems
Melanie Wood
4:30pm|S-101

The Cohen-Lenstra Heuristics conjecturally give the distribution of class groups of imaginary quadratic fields. Since, by class field theory, the class group is the Galois group of the maximal unramified abelian extension, we can consider the Galois...

Mathematical Conversations

The Uncertainty Principle
Charles Fefferman
6:30pm|Dilworth Room

This talk recalls how Gromov's classic non-squeezing theorem from symplectic geometry was first conjectured, based on a connection between eigenvalue problems from PDE and the uncertainty principle from elementary quantum mechanics.

Public Lecture: Claude E. Shannon

5:30pm
Speaker: Sergio Verdú Time: 5:30pm Location Wolfensohn Hall

One of the key scientific contributions of the 20th century, Claude Shannon’s “A Mathematical Theory of Communication” created the field of...

Analysis/Mathematical Physics Seminar

Free dynamics of a tracer particle in a Fermi sea
1:30pm|S-101

The talk is about the dynamics of a tracer particle coupled strongly to a dense non-interacting electron gas in two dimensions. I will present a recent result that shows that for high densities the tracer particle moves freely for very long times.

Joint IAS/Princeton University Symplectic Geometry Seminar

The gauged symplectic sigma-model
Constantin Teleman
1:30pm|S-101

I will recall the construction of the space of states in a gauged topological A-model. Conjecturally, this gives the quantum cohomology of Fano symplectic quotients: in the toric case, this is Batyrev’s presentation of quantum cohomology of toric...

Homological Mirror Symmetry Reading Group

Gamma class from Gauged Linear Sigma Models and B-brane transport
10:45am|Dilworth Room

I'll explain the main result on my paper with Kentaro 1308.2438 [hep-th], which recovers (and generalizes) Iritani's central charge expression, that can be found, for example, in 0903.1463[math.AG]. For this physics derivation I'll have to introduce...
