The circular law for non-Hermitian random band matrices up to bandwidth $N^{1/2 + c}$

Yi Han

We consider inhomogeneous square random matrices of size $N$ with independent entries of mean 0 and finite variance. We assume that the variance profile of this matrix is doubly st…

Invertibility for non-Hermitian and symmetric random band matrices with sublinear bandwidth and discrete entries

Yi Han

A well-known result in random matrix theory, proven by Kahn, Komlós and Szemerédi in 1995, states that a square random matrix with i.i.d. uniform ${\pm 1}$ entries is invertible…

Spectral radius concentration for inhomogeneous random matrices with independent entries

Yi Han

Let $A$ be a square random matrix of size $n$ , with mean zero, independent but not identically distributed entries, with variance profile $S$ . When entries are i.i.d. with unit var…
