摘要
考虑了一类特殊的双色有向图,它的未着色图中有n+2个顶点,包含一个(n+1)-圈和一个(n2+1)圈,给出了本原条件和指数界,并对极图进行了刻划.
In this paper, we consider the special two -colored digraphs whose uncolored digraph has n + 2 vertices n + 1 ) - cycle. We give some primitive conditions and bound on the and consists of one ( n + 1 ) - cycle and one ( n/2- exponents. At last, we give the characterizations of extremal two - colored digraphs .
