Consider a square matrix with independent and identically distributed entries of zero mean and unit variance. It is well known that if the entries have a finite fourth moment, then, in high dimension, ...

We consider the skew Laplacian matrix of a digraph G → obtained by giving an arbitrary direction to the edges of a graph G having n vertices and m edges. We obtain an upper bound for the skew ...

For example, novel studies in spectral graph theory have advanced our understanding of the signless Laplacian matrix and the Aα‐matrix, yielding improved lower bounds on the spectral radius and ...
