Universality for Orthogonal and Symplectic Ensembles
Percy Deift
2:00pm|S-101

This is joint work with Dimitri Gioev. The speaker will show how to prove universality in the bulk and at the edge for orthogonal and symplectic ensembles of random matrices with weights of the form exp(-V(x))dx. The method follows the formalism of...

Paley Graphs and the Combinatorial Topology of the Bruhat Decomposition
Ron Livnè
2:00pm|S-101

Paley graphs are well-known combinatorial objects which have many interesting properties. Many of these properties come from their symmetry under the automorphisms x-->ax+b of the affine line over a finite field F with q elements (q=4m+1). We...

Computer Science/Discrete Mathematics Seminar II

Cryptography and the P vs NP Question
10:30am|S-101

A fundamental question in cryptography is whether the existence of hard on average problems can be based solely on the assumption that P not equal to NP (more precisely, NP not in BPP). The commonly held belief that average-case hardness requires...

Universality for Mathematical and Physical Systems
Percy Deift
4:00pm|S-101

All physical systems in equilibrium obey the laws of thermodynamics. In other words, whatever the precise nature of the interaction between the atoms and molecules at the microscopic level, at the macroscopic level, physical systems exhibit...
