TWO CLASSES OF BICYCLIC GRAPHS ARE DETERMINED BY THEIR LAPLACIAN SPECTRUM
A graph G is said to be determined by its Laplacian spectrum if any graph having the same Laplacian spectrum as G is isomorphic to G. In this paper, we show that two classes of bicyclic graphs are determined by their Laplacian spectra.
spectra of graphs, cospectral graphs, bicyclic graphs, DS graphs.
