摘要：In 1941, Turan proved the famous Turan theorem, i.e., If G is a graph which does not contain Kr+1 as its subgraph, then the edge number of G is no more than the Turan graph Tn,r,which started the extremal theory of graphs. In this talk, we will introduce the spectral Turan-Type results which are associated with the adjacency matrix, signless Laplacian matrix. Moreover, some open problems in this field are proposed.
