摘要：

Let G = (V, E) be a finite graph with n vertexes; the matrix A, D denote the adjacency matrix and the diagonal matrix of a graph G respectively. The matrix D+A is called the signless Laplacian. In this paper, the authors consider three mutually related operations on graphs. These are a unary operation: the complementation of a graph, and two binary operations: the direct sum and the complete product of graphs.
