三种定义关于an action of a group on a set 这里只说明第三种,我认为最好理解。 定义一个映射Φ:G→SX 即将群元素g映射成了一种permutation,就是一种ϕ:X→X,的映射。所以是对X的群作用。 如果我们再给这个映射满足一定条件例如, 2.Φ(1G)=identitypermutation,就是X中元素还映射到自己。
This chapter, combinatorially is intended to be a forerunner to the next chapter 15, where purely combinatorial applications of group action in the form of Polya theory are discussed. However, there appears to be sufficiently large interesting material on group actions with applications that are ...
In this work we deal with group actions on sets. We would like to establish some relations between isotropy subgroups G x, x∈ X of G where G is any group and act on X ( X being a given set). The action of G on X generate an equivalence relation on X, denoted by . In the ...
