一类(k+1)-色有向图的本原指数

Primitive Exponents of a Class of (k+1)-colored Directed Graphs

本文定义了一类具有(k+1)-色(k+1)-圈的有向图D(A),得到了它本原的充要条件,并给出了它的本原指数.

In this paper, we define （k ＋ 1） -colored directed graphs D with （k ＋ 1） -cycles and show a necessary and suffcient condition for these directed graphs to be primitive,obtain the primitive exponent of directed graphs D at the same time.
