报告摘要
In this talk, we will investigate the relationship between the spectrum of a uniform hypergraph and that of its covering; in particular we consider two spectral parameters: the stabilizing index and cyclic index. By using algebraic theory, we find some similarities and differences between the spectra of simple graphs and those of hypergraphs.
