Rescaling Ward Identities in the Random Normal Matrix Model

Creators: Ameur, Yacin; Kang, Nam-Gyu; Makarov, Nikolai

Abstract

We study spacing distribution for the eigenvalues of a random normal matrix, in particular at points on the boundary of the spectrum. Our approach uses Ward's (or the "rescaled loop") equation—an identity satisfied by all sequential limits of the rescaled one-point functions.
