关于generalized characters的一个注记

A note on generalized characters

S J Bhatt, H V Dedania

摘要:

对于紧生成的LCA群$G$,证明了$G$上所有广义特征标的集合$H(G)$是LCA群,且$H(G) = \dg$($G$的对偶群)当且仅当$G$是紧的.这两个结果失败的任意LCA组。进一步地,如果$G$是第二可数的,则具有归纳极限拓扑的交换卷积代数$\ccg$的Gel'fand空间与$\hg$拓扑同胚.

英文摘要:

For a compactly generated LCA group $G$, it is shown that the set $H(G)$ of all generalized characters on $G$ equipped with the compact-open topology is a LCA group and $H(G) = \dg$ (the dual group of $G$) if and only if $G$ is compact. Both results fail for arbitrary LCA groups. Further, if $G$ is second countable, then the Gel'fand space of the commutative convolution algebra $\ccg$ equipped with the inductive limit topology is topologically homeomorphic to $\hg$.
