Regular Fuzzy Closed Sets and Extensions of a Double Fuzzy Topological Space

Vivek S, Sunil C Mathew

Abstract


This paper investigates how the extensions of a double fuzzy topological space affect its regular fuzzy closed sets. While some type of extensions leave all the regular fuzzy closed sets intact, there are regular fuzzy closed sets which remain so under all its extensions.
