摘要
引进了拓扑空间中强半准开集、强半准闭集、强半准闭包算子、强半准内部算子、强半准连续等概念,讨论了它们的性质,给出了Kuratowski十四集定理的推广形式,建立了强半准连续与已有的相关概念之间的联系.
In this paper, strongly semi-preopen sets, strongly semi-preelosed sets, strong semi-preclosure, strong semi-preinterior and strong semi-precontinuity in topological spaces are introduced, their properties are studied, and Kuratowski's fourteen sets theorem is given. Also their relationship with some related notions is set up.
