The maximal spectral radius of the uniform unicyclic hypergraph with perfect matchings

Rui Sun, Wen-Huan Wang, Zhen-Yu Ni

Let $U (n, k)$ and $Γ (n, k)$ be the set of the $k$ -uniform linear and nonlinear unicyclic hypergraphs having perfect matchings with $n$ vertices respectively, where $n\geq k…

On the spectral radius of uniform weighted hypergraph

Rui Sun, Wen-Huan Wang

Let $Q_{k, n}$ be the set of the connected $k$ -uniform weighted hypergraphs with $n$ vertices, where $k, n \geq 3$ . For a hypergraph $G \in Q_{k, n}$ , let $\mathcal{A}…
