Abstract: In this paper we obtain the following results: (1)Perfect mappings preserve C-stratifiable(C-semi-stratifiable,KC- semi-stratifiable)spaces. (2)The image of a C-stratifiable space under a closed mapping need not be C-semi-stratifiable space. (3)The image of a C-stratifiable space under a pseudo-open K-mapping is a C-semi-stratifiable space.
