An Inequality for the Signless Laplacian Index of a Graph Using the Chromatic Number
and
BibTeX referenceLet Q = D + A denote the signless Laplacian matrix of a graph G of order n, where D is the diagonal matrix of the degrees and A the adjacency matrix of G. Let q1 denote the index of Q and the chromatic number of G. In this note we prove that
