Limiting Spectral Distributions of Sums of Products of Non-Hermitian Random Matrices

H. Kösters, A. Tikhomirov

For fixed $l,m\ge 1$, let ${\mathbf{X}}_n^{(0)},{\mathbf{X}}_n^{(1)},\dots ,{\mathbf{X}}_n^{(l)}$ be independent random $n\times n$ matrices with independent entries, let $\mathbf{F}_n^…
