线有向图;
In this paper, we show that under the condition that the minimum degree is at least 3, the iterated line digraph of a super-arc-connected digraph is super-connected.
本文证明了,在最小度至少为3的前提下超弧连通有向图的迭代线图是超点连通的。
By using the matrix representation of a digraph, some results about the index of convergence and period of a line digraph are obtained.
采用有向图的矩阵表示,得到了线有向图的幂敛指数和周期的有关结果。
