A proof of a conjecture on the distance spectral radius

Yanna Wang, Bo Zhou

A cactus is a connected graph in which any two cycles have at most one common vertex. We determine the unique graph that maximizes the distance spectral radius over all cacti with…

Normalized Laplacian eigenvalues of hypergraphs

Leyou Xu, Bo Zhou

In this paper, we give tight bounds for the normalized Laplacian eigenvalues of hypergraphs that are not necessarily uniform, and provide an edge version interlacing theorem, a Che…

Proof of a conjecture on distribution of Laplacian eigenvalues and diameter, and beyond

Leyou Xu, Bo Zhou

Ahanjideh, Akbari, Fakharan and Trevisan proposed a conjecture in [Linear Algebra Appl. 632 (2022) 1--14] on the distribution of the Laplacian eigenvalues of graphs: for any connec…

On extremal leaf status and internal status of trees

Haiyan Guo, Bo Zhou

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