论文摘要
在本文中，我们提供了足够的条件，在该条件下，拓扑组的子群是一个子组，增加了\ cite {kosh can，kosh can，axioms，forum，hof，cc，cc，cc，cc，cc，cc，cc，cc，cc，cc，cc，cc，cc，cc，cc，cc，诸如局部紧凑，紧凑，紧凑，轻巧的紧凑和顺序的紧凑性和顺序压实性），使得分类组成为一组人。在我们的工作中，我们证明了拓扑组的封闭的封闭的预剖面子群是半群，就像拓扑组的开放式伪型单体一样。
In this paper we give sufficient conditions under which a subsemigroup of a topological group is a subgroup, adding to the results given in \cite{Kosh, can, axioms, forum, Hof, cc, locally} where conditions exist (such as locally compactness, compactness, feeble compactness and sequential compactness) for a semigroup to be a group. In our work we proved that closed precompact subsemigroups of topological groups are semigroups, just like open pseudocompact monoids of topological groups.
