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 is defined as , where …
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…
Spectral conditions of complement for some graphical properties
Guidong Yu, Yi Fang, Yi Xu
L.H. Feng at el \cite{feng4} present sufficient conditions based on spectral radius for a graph with large minimum degree to be -path-coverable and -Hamiltonian. Motivated by…
Spectral Radius and Hamiltonicity of graphs
Guidong Yu, Yi Fang, Yizheng Fan +1
In this paper, we study the Hamiltonicity of graphs with large minimum degree. Firstly, we present some conditions for a simple graph to be Hamilton-connected and traceable from ev…
Spectral Condition for a Graph to be Hamiltonian with respect to Normalized Laplacian
Yi-Zheng Fan, Gui-Dong Yu
Let G be a graph and let Δ,δbe the maximum and minimum degrees of G respectively, where Δ/δ<c<\sqrt{2} and c is a constant. In this paper we establish a sufficient spectral conditi…
