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.

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 ...

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

Sobriety of crisp and fuzzy topological spaces [PDF]
, 2004 The objective of this thesis is a survey of crisp and fuzzy sober topological spaces. We begin by examining sobriety of crisp topological spaces. We then extend this to the L- topological case and obtain analogous results and characterizations to those ...

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.

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 ...

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.

Regular L‐fuzzy topological spaces and their topological modifications
International Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 10, Page 687-695, 2000., 2000 For L a continuous lattice with its Scott topology, the functor ιL makes every regular L‐topological space into a regular space and so does the functor ωL the other way around. This has previously been known to hold in the restrictive class of the so‐called weakly induced spaces.
