On the Signless Laplacian Spectral Moment of Graphs

چکیده مقاله

Suppose G be a graph with signless Laplacian eigenvalues q_1; q_2; ...; q_n. The signless Laplacian spectral moments of G is defined T_k(G) = sum of (q_i)^k, i=1,2,...,n . In this paper we compute T_i(G),0 < i < 6, for any graph G and compare some graphs with respect to signless Laplacian spectral moments.
