Disproof of a conjecture on the edge Mostar index

Fazal Hayat, Shou-Jun Xu, Bo Zhou

For a given connected graph $G$ , the edge Mostar index $M o_{e} (G)$ is defined as $M o_{e} (G) = \sum_{e = uv \in E (G)} ∣ m_{u} (e ∣ G) - m_{v} (e ∣ G) ∣$ , where $m_{u} (e ∣ G)$ and $m_{v} (e ∣ G)$ are respectively…

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…
