摘要：
In this paper, we discuss S-closedness in fuzzy topological spaces, and we give some characterizations of alphaS-closedness. Also, we investigate the image and the inverse image of alphaS-closed spaces under some types of functions and we improve and generalize some results on alphaS-closed spaces in fuzzy setting.
