摘要
A semitopological group (topological group) is a group endowed with a topology for which multiplication is separately continuous (multiplication is jointly continuous and inversion is continuous). In this paper we give some topological conditions on a semitopological group that imply that it is a topological group. In particular, we show that every almost Cech-complete semitopological group is a topological group. Thus we improve some recent results of A. Bouziad. (C) 2001 Elsevier Science B.V.
