摘要
令G是一个简单连通图。若G包含长度为3到n的所有圈,则称图G是泛圈的。基于Wiener指数、Harary指数、距离谱半径和Harary谱半径,提供了图G是泛圈图的充分条件,从而建立了图的代数性质与结构性质之间的紧密联系。
Let G be a simple and connected graph.A graph G is pancyclic if it contains all possible cycles with length from three to the number of vertices.In this paper,we provide sufficient conditions for a graph to be pancyclic in terms of the Wiener index,the Harary index,the distance spectral radius and the Harary spectral radius of a graph,respectively.These results establish the relationship between algebraic properties and structural properties of graphs.
