Fuzzy r-continuous and fuzzy r-semicontinuous maps

We introduce a new notion of fuzzy r -interior which is an extension of Changs fuzzy interior. Using fuzzy r -interior, we define fuzzy r -semiopen sets and fuzzy r - semicontinuous maps which are generalizations of fuzzy semiopen sets and fuzzy semi- continuous maps in Changs fuzzy topology, respectively. Some basic properties of fuzzy r -semiopen sets and fuzzy r -semicontinuous maps are investigated.

Fuzzy strongly (r, s)-semiopen sets

In this paper, we introduce the concepts of fuzzy strongly (r, s)-semiopen sets and fuzzy strongly (r, s)-semicontinuous mappings on the intuitionistic fuzzy topological space in Sostaks sense and then we investigate some of their characteristic properties.

FUZZY r-REGULAR OPEN SETS AND FUZZY ALMOST r-CONTINUOUS MAPS

We introduce the concepts of fuzzy r-regular open sets and fuzzy almost r-continuous maps in the fuzzy topology of Chat- topadhyay. Also we investigate the equivalent conditions of the fuzzy almost r-continuity.

Fuzzy (r, s)-preopen sets

In this paper, we introduce the concepts of fuzzy (r,s)-preopen sets and fuzzy (r,s)-precontinuous mappings on intuitionistic fuzzy topological spaces in Sostaks sense and then we investigate some of their characteristic properties.

Fuzzy strongly (r, s)-semicontinuous, fuzzy strongly (r, s)-semiopen and fuzzy strongly (r, s)-semiclosed mappings

In this paper, we investigate some of characteristic properties of fuzzy strongly (r, s)-semicontinuous, fuzzy strongly (r, s)-semiopen and fuzzy strongly (r, s)-semiclosed mappings on the intuitionistic fuzzy topological space in ?ostak’s sense.

Fuzzy (r,s)-semicontinuous mappings on the intuitionistic fuzzy topological spaces in Šostak's sense

In this paper, we investigate some characterizing theorems for fuzzy (r, s )-semicontinuous, (r, s)-semiopen and (r, s)-semiclosed mappings on the intuitionistic fuzzy topological space in ?ostaks sense.

Intuitionistic fuzzy proximity spaces

We introduce the concept of the intuitionistic fuzzy proximity as a generalization of fuzzy proximity, and investigate its properties. Also we investigate the relationship among intuitionistic fuzzy proximity and fuzzy proximity, and intuitionistic fuzzy topology.

Fuzzy pairwise (r; s)-irresolute mappings

In this paper, we introduce the concepts of fuzzy pairwise (r, s)-irresolute, fuzzy pairwise (r, s)-presemiopen and fuzzy pairwise (r, s)-presemiclosed mappings in smooth bitopological spaces and then we investigate some of their characteristic properties.

Fuzzy β-(r, s)-Open Sets in Smooth Bitopological Spaces

We introduce and investigate the concepts of (T i , T j )-fuzzy β-(r, s)-open sets, (T i , T j )-fuzzy β-(r, s)-closed sets and fuzzy pairwise β-(r, s)-continuous mappings in smooth bitopological spaces.

Fuzzy Pairwise β-(r, s)-continuous Mappings

We introduce the concepts of fuzzy pairwise β-(r, s)-continuous mappings and fuzzy pairwise β-(r, s)-open mappings in smooth bitopological spaces and then we investigate some of their characteristic properties.
