摘要 研究了圆可分解的局部半完全有向图D的(i,k)步竞争图Ci,k(D).利用圆可分解有向图的结构以及(i,k)步竞争图的定义,根据对D中任意两个顶点之间的距离关系的讨论,得出了D中任意两个顶点在Ci,k(D)中相邻的一个充分必要条件.由此,刻画了有向图D的(i,k)步竞争图的结构. The (i, k )-step competition graph Ci.k (D) of a round decomposable locally semicomplete digraph was studied. Using the structure of a round decomposable digraph and the definition of the ( i, k ) - step com- petition graph, a sufficient and necessary condition for any two vertices of D to be adjacent in Ci.k (D) was given. Consequently, the structure of the (i, k )- step competition graph Ci.k (D) is characterized.
