Let G be a simple graph with vertices v 1 , v 2 , . . . , v n , of degrees = ) is called the signless Laplacian spectral radius or Q -spectral radius of G. Denote by ฯ‡(G) the chromatic number for a graph G. In this paper, for graphs with order n, the extremal graphs with both the given chromatic num
