摘要
一个本原不可幂带号有向图S的基指数l(S)是指使得在S中,从任意一点u到任意一点v都有一对长为l的SSSD途径的最小整数l.本文将完全刻划n阶本原不可幂简单图的基指数集.
The base l(S) of a primitive non - powerful signed digraph S is the least integer l such that there exist a pair of SSSD walks of length l from each vertex u to each vertex v in S. In this paper, we determine the base sets of primitive non- powerful signed simple graphs.
