Maximum reciprocal degree resistance distance index of unicyclic graphs

Gui-Dong Yu, Xing-Xing Li, Gai-Xiang Cai

The reciprocal degree resistance distance index of a connected graph $G$ is defined as $R D R (G) = {u, v} \subseteq V (G) \sum \frac{d _{G} ( u ) + d _{G} ( v )}{r _{G} ( u , v )}$ , where $r_{G} (u, v)$ …

Some Sufficient Conditions on Pancyclic Graphs

Guidong Yu, Tao Yu, Axiu Shu +1

A pancyclic graph is a graph that contains cycles of all possible lengths from three up to the number of vertices in the graph. In this paper, we establish some new sufficient cond…

Wiener Index, Hyper-wiener Index, Harary Index and Hamiltonicity of graphs

Guidong Yu, Lifang Ren, Gaixiang Cai

In this paper, we discuss the Hamiltonicity of graphs in terms of Wiener index, hyper-Wiener index and Harary index of their quasi-complement or complement. Firstly, we give some s…
