Local Semicircle Law for Curie-Weiss Type Ensembles

Probability 2021-04-21 v2

Abstract

We derive and compare various forms of local semicircle laws for random matrices with exchangeable entries which exhibit correlations that decay at a very slow rate. In fact, any ll-point correlation will decay at a rate of Nl/2N^{-l/2}. We call our ensembles \emph{of Curie-Weiss type}, and Curie-Weiss(β\beta)-distributed entries are admissible as long as β1\beta\leq 1.
