摘要：

For a graph G and a real number alpha (alpha not equal 0, 1), the graph invariant S-alpha(G) is the sum of the alpha th power of the signless Laplacian eigenvalues of G. Let IE(G) denote the incidence energy of G, i.e., IE(G) = S-1/2 (G). This note presents some properties and bounds for S-alpha(G) and IE(G).
