High-ordered spectral characterizations of graphs

Lixiang Chen, Lizhu Sun, Changjiang Bu

The spectrum of the $k$ -power hypergraph of a graph $G$ is called the $k$ -ordered spectrum of $G$ .If graphs $G_{1}$ and $G_{2}$ have same $k$ -ordered spectrum for all positive integer…

The reduced formula of the characteristic polynomial of hypergraphs and the spectrum of hyperpaths

Changjiang Bu, Lixiang Chen

In this paper, we give a reduced formula of the characteristic polynomial of $k$ -uniform hypergraphs with a pendant edge. And the explicit characteristic polynomial and all distinc…
