The limit of the operator norm for random matrices with a variance profile
Dimitris Cheliotis, Michail Louvaris
In this work we study symmetric random matrices with variance profile satisfying certain conditions. We establish the convergence of the operator norm of these matrices to the larg…

On the spectral radius of the non-backtracking matrix of the configuration model
Michail Louvaris, Daniel T. Wise, Gal Yehuda
We prove a concentration result for the leading eigenvalue of the non--backtracking matrix of the configuration model under the assumption of uniformly bounded degrees. Let den…
