On the connective eccentricity index of two types of trees

Zikai Tang, Lingyao Jiang, Hanyuan Deng

The connective eccentricity index $ξ^{ce} = \sum_{u \in V} \frac{d ( u )}{ε ( u )}$ , where $ε (u)$ and $d (u)$ denote the eccentricity and the degree of the vertex $u$ ,…

On a Conjecture of Randić Index and Graph Radius

Hanyuan Deng, Zikai Tang, Jie Zhang

The Randić index $R (G)$ of a graph $G$ is defined as the sum of $(d_{i} d_{j})^{- 1/2}$ over all edges $v_{i} v_{j}$ of $G$ , where $d_{i}$ is the degree of the vertex $v_{i}$ in $G$ . The radius…

On the Main Signless Laplacian Eigenvalues of a Graph

Hanyuan Deng, He Huang

A signless Laplacian eigenvalue of a graph $G$ is called a main signless Laplacian eigenvalue if it has an eigenvector the sum of whose entries is not equal to zero. In this paper,…
