报告摘要
In 1941, Turan proved the famous Turan theorem, i.e., If G is a graph which
does not contain $K_{r+1}$ as its subgraph, then the edge number of G is no more than
the Turan graph $T_{n,r}$, 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.
