内容摘要:
The spectral theory of graphs and hypergraphs is a very active and important research topic in graph theory. In this talk, we first give a brief introduction on the tensor spectral theory and the extremal spectral problems of graphs and hypergraphs. Then we present two approach results to establish the connection between spectral radius of the adjacency tensor and structural properties of a hypergraph. By these two methods, we obtain several spectral versions of Turán-type results on linear k-uniform hypergraphs.
