Abstract
We consider random matrices of the form , where is the adjacency matrix of a uniform random -regular directed graph on vertices, with for some fixed , and is an matrix of iid centered random variables with unit variance and finite -th moment (here denotes the matrix Hadamard product). We show that as , the empirical spectral distribution of converges weakly in probability to the normalized Lebesgue measure on the unit disk.
