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 geometry connectivity of hypergraphs

Chunli Deng, Lizhu Sun, Changjiang Bu

Let $G$ be a $k$ -uniform hypergraph, $L_{G}$ be its Laplacian tensor. And $β (G)$ denotes the maximum number of linearly independent nonnega…

Bounds on the $α$ -distance spectrum of graphs

Yang Yang, Lizhu Sun, Changjiang Bu

For a simple, undirected and connected graph $G$ , $D_{α} (G) = α T r (G) + (1 - α) D (G)$ is called the $α$ -distance matrix of $G$ , where $α \in [0, 1]$ , $D (G)$ is the distance matrix of $G$ ,…

Spectral properties of general hypergraphs

Changjiang Bu, Jiang Zhou, Lizhu Sun

In this paper, we investigate spectral properties of the adjacency tensor, Laplacian tensor and signless Laplacian tensor of general hypergraphs (including uniform and non-uniform…
