Mesoscopic eigenvalue statistics for Wigner-type matrices (2301.01712v1)
Published 4 Jan 2023 in math.PR
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 $T(z,\zeta)$ and a general class of related quantities involving two resolvents at nearby spectral parameters.
