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,…

Bicyclic graphs with exactly two main signless Laplacian eigenvalues

He Huang, Hanyuan Deng

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,…
