摘要
利用拓扑空间中的内部、闭包、半内部、半闭包等算子,给出了正则开集、准开集、半准开集、β开集、半正则半开集、正则半开集等一些近似开集的等价性质.
In this paper, we obtain equivalent properties of some nearly open sets, such as regularly open sets, pre-open sets, semi-preopen sets, β-open sets, semi-regularly semi-open sets and regularly semi-open sets, utilizing some defined operators of interior and closure.
