Fuzzy neighborhood structures on partially ordered groups
International Journal of Mathematics and Mathematical Sciences, Volume 31, Issue 6, Page 359-365, 2002., 2002 Ahsanullah (1988) showed the compatibility between group structures and I‐fuzzy neighborhood systems. In this paper, we require not only that the I‐fuzzy neighborhood systems be compatible with the group structures, but also compatible with the order relation, in one sense or another.

On generalized fuzzy strongly semiclosed sets in fuzzy topological spaces
International Journal of Mathematics and Mathematical Sciences, Volume 30, Issue 11, Page 651-657, 2002., 2002 We introduce the concept of generalized fuzzy strongly semiclosed, generalized fuzzy almost‐strongly semiclosed, generalized fuzzy strongly closed, and generalized fuzzy almost‐strongly closed sets. In the light of these definitions, we also define some generalizations of fuzzy continuous functions and discuss the relations between these new classes of

On I-convergence of nets of functions in fuzzy metric spaces
Open MathematicsIn this paper, we introduce ideal versions of semi-α convergence, semi-exhaustiveness and semi uniform convergence of nets of functions between two fuzzy metric spaces, and obtain some properties of them.

Uniform Continuity in Fuzzy Metric Spaces [PDF]
, 2001 With the help of appropriate fuzzy notions of equinormality and Lebesgue property, several characterizations of those fuzzy metric spaces, in the sense of George and Veeramani, for which every real valued continuous function is uniformly continuous ...

Journal of Mathematics, Volume 2025, Issue 1, 2025.In this work, we modify the definition of intuitionistic fuzzy points so that the definition is concise, generalizes fuzzy points, and excludes 0˜. We establish new forms of relations between intuitionistic fuzzy sets and demonstrate that every quasi‐coincidence relation is coincidence.

Bounded solutions for fuzzy integral equations
International Journal of Mathematics and Mathematical Sciences, Volume 31, Issue 2, Page 109-114, 2002., 2002 We study conditions under which the solutions of a fuzzy integral equation are bounded.

Characterization of fuzzy neighborhood commutative division rings II [PDF]
, 1995 In [4] we produced a characterization of fuzzy neighborhood commutative division rings; here we present another characterization of it in a sense that we minimize the conditions so that a fuzzy neighborhood system is compatible with the commutative ...

Fuzzy r‐continuous and fuzzy r‐semicontinuous maps
International Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 1, Page 53-63, 2001., 2001 We introduce a new notion of fuzzy r‐interior which is an extension of Chang′s 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 semicontinuous maps in Chang′s fuzzy topology, respectively.
