1) power map
幂映射
1.
Let R be a commutative ring and f:R→R a power map defined by f(r)=r￣nLet x and y be two periodic points of f witli periods k and l respectively.
设Ｒ是个交换环，带离散拓扑，是由ｆ（ｒ）＝ｒ￣ｎ（任ｒ∈Ｒ）定义的幂映射。
2) plastic of the power mapping
幂塑映射
1.
in this paper, the concept of the plastic of the power mapping is introduced, With the relationship of sequence, We discussed the properties of the plastic of the power mapping, Some of the results for a class of the dots in space under the condition for the power transformation are presented.
引入幂塑映射概念,利用序关系讨论了幂塑映射的性质,并给出了一类空间点在幂变换下的一些结果。
3) idempotent mapping
幂等映射
1.
The k-th idempotent mapping on the set [1,n] is firstly defined in this paper,the counting formula of which is obtained by circulating decomposition of permutation groups.
本文首先给出集[1,n]上k-次幂等映射的概念,用置换群的循环分解给出集[1,n]上k-次幂等映射的计数公式,接着定义了连象映射和保小映射,不但得到它们的计数公式,还得到一个第2类斯特林数的关系式及保小映射总数指母函数系数的变化趋势,最后给出交错映射及上下置换的概念并给出关于上下置换指母函数简明表达式的一个简单证明。

5) idempotent-preserving map
保幂等映射
6) parametric power map
参数幂映射
