摘要
本论文利用半连续集值映射的插入给出具有层型结构空间的一些等价刻画.也引入了K-lower和K-upper集值映射,利用此概念给出了k-半层空间以及k-MCM的刻画.
In this paper,we give some characterizations of stratifiable and semistratifiable spaces by the insertion of semi-continuous set-valued mappings. Also,we introduce the K-lower and K-upper set-valued mappings and, using them,give some characterizations of k-semi-stratifiable spaces and k-MCM（kβ）spaces.
