Abstract

It is known that two regular graphs of minimum degree 2 are cospectral if and only if they have the same Ihara zeta function. In this article we present other families of graphs for which the spectrum of the adjacency matrix and the Ihara zeta function determine each other. © 2014 Published by Elsevier B.V.
