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…

Estrada index and subgraph centrality of hypergraphs via tensors

Hong Zhou, Lizhu Sun, Changjiang Bu

Uniform hypergraphs have a natural one-to-one correspondence to tensors. In this paper, we investigate the Estrada index and subgraph centrality of an $m$ -uniform hypergraph $\math…
