Perturbation of the α-spectral radius of complete multipartite graphs

上海师范大学学报. 自然科学版
Let G be a graph and α∈[0, 1), Nikiforov merged the adjacency matrix and the signless Laplacian matrix to Aα(G)=αD(G)+(1-α)A(G), where D(G), A(G) are the degree diagonal matrix and the adjacency matrix of G, respectively.
