报告摘要：Turán problems of graphs or Hypergraphs are the core issue in the extremal graph theory. In this talk, we first give a brief introduction on the tensor eigenvalues and the problem on the spectral version of Turán-type problems over uniform hypergraphs. Then we develop two new tools to establish the connection between spectral radius of the adjacency tensor and structural properties of a hypergraph. By these two methods, several spectral versions of Turán-type results on linear k-uniform hypergraphs are obtained.
