给出了层次闭包空间的概念,定义并研究了层次闭包空间的子空间和由分明闭包空间诱导的层次闭包空间,讨论了层次闭包空间的D_a-T_i(i=0,1,2)分离性.
In this paper,we investigate a nontion of stratiform closure space,define and study the subspace of stratiform closure space and the induced stratiform closure spaces by crisp closutre spaces, and discuss the separations of stratiform closure space.
