Abstract
The Brualdi-Solheid-Tur?n type problem has attracted wide attention
recently. Let F be a set of graphs. A graph G is F -free if it does not
contain any element of F as a subgraph. In this paper, when F1 = {W5,C6} and
F2 = {F5}, we determine the maximum signless Laplacian spectral radius of
Fi-free graph with n vertices, respectively and depict the corresponding
extremal graph for i = 1,2.
