An $(iota,kappa)$-fuzzy $M$ closed and $(iota,kappa)$ - generalized fuzzy $M$ closed sets in double fuzzy topological spaces

Abstract

In double fuzzy topological spaces, (ι, κ)-fuzzy θ-closed, (ι, κ)-fuzzy M-closed sets and (ι, κ)-generalized fuzzy M-closed sets are introduced. Also we study some of their properties. Keywords (ι, κ)-fuzzy θ-closed, (ι, κ)-fuzzy M-closed sets, (ι, κ)-generalized fuzzy M-closed sets,(ι, κ)-generalized fuzzy M-interior, (ι, κ)-generalized fuzzy M-closure.
