报告摘要:

In this talk, some results on the tensor spectra of power hypergraphs, hypertrees and graphs are introduced, which includes some formulas on the eigenvalues and characteristic polynomials of power hypergraphs and hypertrees, and some spectral extremal results on the tensor spectra of graphs. In addition, some applications of tensor spectra of graphs and hypergraphs are also introduced. This is a joint work with Chunmeng Liu, Lixiang Chen, Lizhu Sun and Jiang Zhou.
