Wiener index, Harary index and Hamiltonicity of graphs
Hongbo Hua, Bo Ning
In this paper, we prove tight sufficient conditions for traceability and Hamiltonicity of connected graphs with given minimum degree, in terms of Wiener index and Harary index. We…
Spectral radius and Hamiltonian properties of graphs, II
Jun Ge, Bo Ning
In this paper, we first present spectral conditions for the existence of in graphs (2-connected graphs) of order , which are motivated by a conjecture of Erdős. Then w…
The Randić index and signless Laplacian spectral radius of graphs
Bo Ning, Xing Peng
Given a connected graph , the Randić index is the sum of over all edges of , where and are the degree of vertices…
Cyclability of -cycles in graphs
Ruonan Li, Bo Ning, Shenggui Zhang
Let be a graph on vertices and a vertex sequence of with ( for all , ). If for any succ…
Spectral analogues of Moon-Moser's theorem on Hamilton paths in bipartite graphs
Binlong Li, Bo Ning
In 1962, Erdős proved a theorem on the existence of Hamilton cycles in graphs with given minimum degree and number of edges. Significantly strengthening in case of balanced biparti…
