On the $α$ -spectral radius of hypergraphs

Haiyan Guo, Bo Zhou, Bizhu Lin

For real $α \in [0, 1)$ and a hypergraph $G$ , the $α$ -spectral radius of $G$ is the largest eigenvalue of the matrix $A_{α} (G) = α D (G) + (1 - α) A (G)$ , where $A (G)$ is the adjacency matrix of…

On extremal leaf status and internal status of trees

Haiyan Guo, Bo Zhou

For a vertex $u$ of a tree $T$ , the leaf (internal, respectively) status of $u$ is the sum of the distances from $u$ to all leaves (internal vertices, respectively) of $T$ . The min…

Minimum status, matching and domination of graphs

Caixia Liang, Bo Zhou, Haiyan Guo

The minimum status of a graph is the minimum of statuses of all vertices of this graph. We give a sharp upper bound for the minimum status of a connected graph with fixed order and…
