Some $α$ -spectral extremal results for some digraphs

Haiying Shan, Feifei Wang, Changxiang He

In this paper, we characterize the extremal digraphs with the maximal or minimal $α$ -spectral radius among some digraph classes such as rose digraphs, generalized theta digraphs an…

The smallest spectral radius of bicyclic uniform hypergraphs with a given size

Haiying Shan, Zhiyi Wang, Feifei Wang

Identifying graphs with extremal properties is an extensively studied topic in spectral graph theory. In this paper, we study the log-concavity of a type of iteration sequence rela…

On some properties of the $α$ -spectral radius of the $k$ -uniform hypergraph

Feifei Wang, Haiying Shan, Zhiyi Wang

In this paper we show how the $α$ -spectral radius changes under the edge grafting operations on connected $k$ -uniform hypergraphs. We characterize the extremal hypertree for $α$ -sp…
