有限指数群的Itzkowitz问题

Itzkowitz's problem for group of finite exponent

Ahmed Bouziad, Aicha Bareche

摘要:

Itzkowitz的问题是,如果$G$上的有界左一致连续实值函数是右一致连续的,那么是否每个拓扑群$G$都有相等的左、右一致结构.本文给出了这个问题的一个肯定答案,如果$G$是有界指数的,或者更一般地,如果存在一个整数$p\geq 2$和一个非空开集$U\subset G$,使得幂映射$U\ni g\to g^p\in G$是左(或右)一致连续的.这也解决了问题的周期群是Baire空间。

英文摘要:

Itzkowitz's problem asks whether every topological group $G$ has equal left and right uniform structures provided that bounded left uniformly continuous real-valued function on $G$ are right uniformly continuous. This paper provides a positive answer to this problem if $G$ is of bounded exponent or, more generally, if there exist an integer $p\geq 2$ and a nonempty open set $U\subset G$ such that the power map $U\ni g\to g^p\in G$ is left (or right) uniformly continuous. This also resolves the problem for periodic groups which are Baire spaces.
