A relation on trees and the topological indices based on subgraph

Rui Song, Qiongxiang Huang

A topological index reflects the physical, chemical and structural properties of a molecule, and its study has an important role in molecular topology, chemical graph theory and ma…

The extremal graphs of order trees and their topological indices

Rui Song, Qiongxiang Huang, Peng Wang

Recently, D. Vuki $c ˇ$ evi $c ˊ$ and J. Sedlar in \cite{Vuki} introduced an order " $⪯$ " on $T_{n}$ , the set of trees on $n$ vertices, such that the topologi…

Some new bounds for the signless Laplacian energy of a graph

Peng Wang, Qiongxiang Huang

For a simple graph $G$ with $n$ vertices, $m$ edges and signless Laplacian eigenvalues $q_{1} \geq q_{2} \geq \dots \geq q_{n} \geq 0$ , its the signless Laplacian energy $QE (G)$ i…

The Kirchhoff Index of Enhanced Hypercubes

Ping Xu, Qiongxiang Huang

Let ${e_{1}, \dots, e_{n}}$ be the standard basis of abelian group $Z_{2}^{n}$ , which can be also viewed as a linear space of dimension $n$ over the Galois filed $F_{2}$ , and $ε_{…

The full chracterazation of the graphs with a L-eigenvalue of multiplicity $n - 3$

Daijun Yin, Qiongxiang Huang

Let $G (n, k)$ be the set of connected graphs of order $n$ with one of the Laplacian eigenvalue having multiplicity $k$ . It is well known that $G (n, n - 1) = {K_{n}}$ .…
