笔者首先利用顶点的度和给出了有向图是超级局部边连通的一个最好可能的充分条件,然后提出了二部有向图为极大局部边连通和超级局部边连通的度序列条件.这些结果在网络可靠性分析中有一定应用.
This paper presents a best possible sufficient condition in term of degree sum for a digraph to be super- local -edge -connected. Using degree sequence we give sufficient conditions for a bipartite digraph to be maximally local -edge -connected and super -local -edge -connected. These results have applications in analy- sis of network reliability.
