On fuzzy semi a-open sets and fuzzy semi a-continuous mappings

Abstract EN

In this paper, we extend the notion of semi a-open sets to fuzzy topology space, study some notions based on this new concept and study the relation between fuzzy semi a-open sets and other types of fuzzy open sets.

We also introduce the concept of fuzzy semi a-continuous mapping and other weaker forms of fuzzy semi a-continuous mapping and discuss their relation with fuzzy continuous mapping and other weaker forms of fuzzy continuous mapping.

Counter examples are given to show the non-coincidence of this mapping.
