论文摘要
在本文中,我们继续研究P.S.提出的一般拓扑中的经典问题之一。 Alexandrov:当Hausdorff Space $ X $具有连续的两次培养(凝结)时?我们专注于不仅$ x $,而且还可以在$ y $的基数不超过某些$τ$的情况下,还可以将$ x \ setminus y $凝结到压缩上。
In this paper, we continue to study one of the classic problems in general topology raised by P.S. Alexandrov: when a Hausdorff space $X$ has a continuous bijection (a condensation) onto a compactum? We concentrate on the situation when not only $X$ but also $X\setminus Y$ can be condensed onto a compactum whenever the cardinality of $Y$ does not exceed certain $τ$.
