摘要 对第二纲的仿紧Quarter可层化空间进行了研究,证明了这类空间含有σ闭离散的稠密子集.同时给出了实数集的子集是消去拓扑半群,但是不是Quarter可层化空间. The second category and paracompact Quarter-stratifiable spaces are stadied. All Quarter-stratifiable spaces have a σ- closed-discrete dense subset if this space is second category and paracompact. In addition, an example is given, which is semisubgroup of R, but not quarter-stratifiable.
