$H$ -闭拟拓扑群

$H$-closed quasitopological groups

Serhiy Bardyla, Oleg Gutik, Alex Ravsky

摘要:

一个$H$ -闭拟拓扑群是一个包含在每个Hausdorff拟拓扑群中作为闭子空间的Hausdorff拟拓扑群。我们得到了拟拓扑群是$H$ -闭的一个充分条件,这使我们能够解决Arhangel'skii和Choban的一个问题,并证明了拓扑群$G$在拟拓扑群类中是$H$ -闭的当且仅当$G$是\v <$kov-完备的.此外,我们提出的非紧拟拓扑群的拓扑空间是$H$ -封闭的例子。

英文摘要:

An $H$-closed quasitopological group is a Hausdorff quasitopological group which is contained in each Hausdorff quasitopological group as a closed subspace. We obtained a sufficient condition for a quasitopological group to be $H$-closed, which allowed us to solve a problem by Arhangel'skii and Choban and to show that a topological group $G$ is $H$-closed in the class of quasitopological groups if and only if $G$ is Ra\vıkov-complete. Also we present examples of non-compact quasitopological groups whose topological spaces are $H$-closed.
