Universality of Random Matrices and Local Relaxation Flow

Abstract

We consider $N\times N$ symmetric random matrices where the probability distribution for each matrix element is given by a measure $ν$ with a subexponential decay. We prove that the eigenvalue spacing statistics in the bulk of the spectrum for these matrices and for GOE are the same in the limit $N \to \infty$. Our approach is based on the study of the Dyson Brownian motion via a related new dynamics, the local relaxation flow.

A minor error in the proof of Lemma 2.2 has been corrected and an additional technical condition was added to Cor. 2.4. Final version with some more details in Prop 4.1 was added on Nov 24
