Spectral characterization of a specific class of trees

Combinatorics 2010-11-04 v1

Abstract

In this paper, it is shown that the graph T4(p,q,r)T_4(p,q,r) is determined by its Laplacian spectrum and there are no two non-isomorphic such graphs which are cospectral with respect to adjacency spectrum.
