建立时候:  2021/08/26  龚惠英   阅读次数:   前往

报告主题:基于张量谱实际的超图的Turán题目(Hypergraph Turán problems via tensor spectral theory)

报 告 人:常安 传授(福州大学)

报告时候:2021年8月26日(周四) 19:00

参会体例:腾讯集会

集会ID:765 883 113

约请人:康丽英

主理部分:理学院数学系

报告择要: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.
