چکیده
A graph G is said to be determined by the spectrum of its Laplacian matrix (DLS) if every with same isomorphic G. In some recent papers it proved that friendship graphs and starlike trees are DLS. If a tree joined merging their vertices degree greater than two, then resulting called path-friendship graph. this paper, graphs, natural generalization trees, also Consequently, using these results we provide solution for an open problem.

THE SPECTRAL DETERMINATION OF THE MULTICONE GRAPHS Kw ▽ C WITH RESPECT TO THEIR SIGNLESS LAPLACIAN SPECTRA
The main aim of this study is to characterize new classes of multicone graphs which are determined by their signless Laplacian spectra. A multicone graph is defined to be the join of a clique and a regular graph. Let C and K w denote the Clebsch graph and a complete graph on w vertices, respectively. In this paper, we show that the multicone graphs K w ▽C are determined by their signless ...
