Mesoscopic eigenvalue statistics for Wigner-type matrices

preprint2023arXivOpen access

Abstract

We prove a universal mesoscopic central limit theorem for linear eigenvalue statistics of a Wigner-type matrix inside the bulk of the spectrum with compactly supported twice continuously differentiable test functions. The main novel ingredient is an optimal local law for the two-point function T(z,ζ)T(z,ζ) and a general class of related quantities involving two resolvents at nearby spectral parameters.
