摘要 设G=(V,E)是连通图.G的离心连通度指标定义为(?)~c(G)=∑_(x∈V)ec(x)deg(x),其中ec(x)是x的离心率,deg(x)是x的度. Let G=(V,E) be a connected graph.The eccentric connectivity index of G is defined asξ~c(G) =Σ_(x∈V)ec(x)deg(x),where ec(x) is the eccentricity of X,deg(x) is the degree of x.We obtain the lower and upper bounds of unicyclic graphs with diameter.d.
