The linear unicyclic hypergraph with the second or third largest spectral radius
Chao Ding, Yi-Zheng Fan, Jiang-Chao Wan
The spectral radius of a uniform hypergraph is defined to be that of the adjacency tensor the hypergraph. It is known that the unique unicyclic hypergraph with the largest spectral…
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 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 conditions for a graph to be Hamilton-connected
Gui-Dong Yu, Yi-Zheng Fan
In this paper we establish some spectral conditions for a graph to be Hamilton-connected in terms of the spectral radius of the adjacency matrix or the signless Laplacian of the gr…
