The extremal $p$ -spectral radius of Berge-hypergraphs

Liying Kang, Lele Liu, Linyuan Lu +1

Let $G$ be a graph. We say that a hypergraph $H$ is a Berge- $G$ if there is a bijection $ϕ : E (G) \to E (H)$ such that $e \subseteq ϕ (e)$ for all $e \in E (G)$ . For any $r$ -uniform hyper…

The $(p, q)$ -spectral radii of $(r, s)$ -directed hypergraphs

Lele Liu, Linyuan Lu

An $(r, s)$ -directed hypergraph is a directed hypergraph with $r$ vertices in tail and $s$ vertices in head of each arc. Let $G$ be an $(r, s)$ -directed hypergraph. For any real numb…

The $α$ -normal labeling method for computing the $p$ -spectral radii of uniform hypergraphs

Lele Liu, Linyuan Lu

Let $G$ be an $r$ -uniform hypergraph of order $n$ . For each $p \geq 1$ , the $p$ -spectral radius $λ^{(p)} (G)$ is defined as \[ λ^{(p)}(G):=\max_{|x_1|^p+\cdots+|x_n|^p=1} r\sum_{\{i_…

On the irregularity of uniform hypergraphs

Lele Liu, Liying Kang, Erfang Shan

Let $H$ be an $r$ -uniform hypergraph on $n$ vertices and $m$ edges, and let $d_{i}$ be the degree of $i \in V (H)$ . Denote by $ε (H)$ the difference of the spectral radius of…
