The effect of a graft transformation on distance signless Laplacian spectral radius of the graphs

Dandan Fan, Guoping Wang, Yinfeng Zhu

Suppose that the vertex set of a connected graph $G$ is $V (G) = {v_{1}, \dots, v_{n}}$ . Then we denote by $T r_{G} (v_{i})$ the sum of distances between $v_{i}$ and all other vertices of $G$ .…

The least signless Laplacian eigenvalue of the complements of bicyclic graphs

Xiaoyun Feng, Guoping Wang

Suppose that $G$ is a connected simple graph with the vertex set $V (G) = {v_{1}, v_{2}, \dots, v_{n}}$ . Then the adjacency matrix of $G$ is $A (G) = (a_{ij})_{n \times n}$ , where $a_{ij} = 1$ i…
