Fuzzy e-regular spaces and strongly e-irresolute mappings

The aim of this paper is to introduce fuzzy (e, almost) e -regular spaces in Sostak s fuzzy topological spaces. Using the r-fuzzy e-closed sets, we de ne r-(r- -, r-e -) e-cluster points and their properties. Moreover, we investigate the relations among r(r- -, r-e -) e-cluster points, r-fuzzy (e, almost) e -regular spaces and their functions.
