1.
On the basis of weakly vertex-transitive graphs and weakly edge-transitive graphs, some properties of weakly 1-arc transitive graphs are obtained and all weakly 1-arc transitive graphs whose order is less than 7 are given; weakly 1/2-transitive graphs are also studied.
在弱点传递图和弱边传递图的研究基础上,本文讨论了弱1-弧传递图的性质,描述了弱1-弧传递图的结构,给出了顶点个数小于7的所有连通的弱1-弧传递图;本文还研究了弱1/2-传递图(即弱边传递而非弱1-弧传递的图),得到了顶点个数最少的弱1/2-传递图,讨论了弱边传递图是弱1-弧传递图的充要条件,并给出了各种对称性之间的区别与联系;本文最后研究了图的弱s-弧传递性(s≥2),证明了对于非二分图,弱s-弧传递性和s-弧传递性是等价的;对于二分图,弱s-弧传递性是由围长g和直径d决定的,而且还得到与s-弧传递性相一致的两个必要条件:即s存在上界(g+2)/2;当s正好达到此上界时是一个直径为g/2的二分图。
