一类特殊本原有向图的m-competition指数

The Competition Index of A Special Class of Primitive Digraphs

对一类含有两种不同圈长的本原有向图的m-competition指数进行了研究,根据图论知识,通过分析本原有向图D与本原有向图D^(n-4),D^(n-2)之间的关系,结合本原有向图m-competition指数的定义,利用集合的运算给出了此类图的m-competition指数.

A class of two different cycle length of primitive digraphs are discussed.According to graph theory,by analyzing the relationship between the primitive digraph D and the primitive digraphD-（n-4）,D-（n-2） and combining with the definition of the m-competition index of a primitive digraph,the exponent of this special class of primitive digraphs is given through the set operations.
