Quantum Ergodicity on Large Regular Graphs
Nalini Anantharaman
2:00pm|S-101

``Quantum ergodicity'' usually deals with the study of eigenfunctions of the Laplacian on Riemannian manifolds, in the high-frequency asymptotics. The rough idea is that, under certain geometric assumptions (like negative curvature), the...

Computer Science/Discrete Mathematics Seminar I

Influences, Traces, Tribes, and Perhaps Also Thresholds
11:15am|S-101

I will describe some recent results and problems regarding influence of sets of variables on Boolean functions: In 1989 Benny Chor conjectured that a balanced Boolean function with n variables has a subset S of size 0.4n with influence (1-c^n) where...

Mathematical Conversations

Quantum Theory and Topos Theory
6:00pm|Dilworth Room

We relate algebraic quantum mechanics (C*-algebras) to topos theory, so as to capture the essence of quantum logic and quantum spaces. Motivated by Bohr's idea that the empirical content of quantum physics is accessible only through classical...

Analysis Seminar

Large Data Dynamics for Nonlinear Dispersive PDEs
3:30pm|S-101

We will discuss recent work on wave evolutions for large data. Particular emphasis will be placed on concentration compactness ideas. Amongst others, we will describe a result for wave equations from R^3 minus the unit ball into the sphere S^3 where...

Joint IAS/Princeton University Number Theory Seminar

Automorphic Levi-Sobolev Spaces, Boundary-Value Problems, and Self-Adjoint Operators
Paul Garrett
4:30pm|S-101

Application of Plancherel's theorem to integral kernels approximating compact period functionals yields estimates on (global) automorphic Levi-Sobolev norms of the functionals. The utility of this viewpoint can be illustrated in reconsideration of...
