Abstract

Let G^s be a signed graph, where G = (V;E) is the underlying simple graph and s : E(G) to
{+, -} is the sign function on E(G). In this paper, we obtain k-th signed spectral moment and k-th signed Laplacian spectral moment of Gs together with coefficients of their signed characteristic polynomial and signed Laplacian characteristic polynomial are calculated.
