摘要: G图是一个简单连通图,图G的离心距离和定义为,其中表示顶点ν的离心率,表示在图G中顶点ν到其它所有顶点的距离和。本文刻画了控制数为γ且具有最大离心距离和的树的结构。该结论是若干已有成果的推广。
Abstract: Let G be a connected graph. The eccentric distance sum of graph G is defined as , where is the eccentricity of the vertex ν and is the sum of all distances from the vertex ν. In this paper, we characterize the tree with domination number γ and the maximal eccentric distance sum. Some known results have been extended.
