一类双色有向图的本原指数的上界

摘要

研究一类双色有向图，其基础有向图仅包含两个圈，分别是n-圈与（3n-1）-圈，并给出了这个双色有向图的本原条件、本原指数上界，以及对达到上界的极图进行了刻画。%A class of two-colored digraphs whose uncolored digraph consists of one n-cycle and one(3n-1)-cycle. Some primitive conditions, an upper bound on the exponent, and the characterizations of the extremal two-colored digraphs.
