Per-Spectral Characterizations Of Some Bipartite Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2017
A graph is said to be characterized by its permanental spectrum if there is no other non-isomorphic graph with the same permanental spectrum. In this paper, we investigate when a complete bipartite graph Kp,p with some edges deleted is determined by its ...
