Complete Hausdorffness and Complete Regularity on Supra Topological Spaces
Journal of Applied Mathematics, Volume 2021, Issue 1, 2021., 2021 The supra topological topic is of great importance in preserving some topological properties under conditions weaker than topology and constructing a suitable framework to describe many real‐life problems. Herein, we introduce the version of complete Hausdorffness and complete regularity on supra topological spaces and discuss their fundamental ...

Journal of Mathematics, Volume 2020, Issue 1, 2020., 2020 In this paper, we define a weak type of soft Menger spaces, namely, nearly soft Menger spaces. We give their complete description using soft s‐regular open covers and prove that they coincide with soft Menger spaces in the class of soft regular ⋆ spaces.

Fuzzy Ideal Supra Topological Spaces
Advances in Fuzzy Systems, Volume 2020, Issue 1, 2020., 2020 In this paper, we introduce the notion of fuzzy ideals in fuzzy supra topological spaces. The concept of a fuzzy s‐local function is also introduced here by utilizing the s‐neighbourhood structure for a fuzzy supra topological space. These concepts are discussed with a view to find new fuzzy supra topologies from the original one.

On Darboux‐Type Differential Inclusions with Uncertainty
Complexity, Volume 2019, Issue 1, 2019., 2019 In this article we prove the existence results for solutions of the Darboux‐type problems in fuzzy partial differential inclusions with local conditions of integral types. We present two problems involving open and closed level sets of a given fuzzy mapping.

On Abstract Economies and Their Applications
Abstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013 We establish a new equilibrium existence theorem of generalized abstract economies with general preference correspondences. As an application, we derive an existence theorem of generalized quasi‐variational inequalities in the general setting of l.c.‐spaces without any linear structure.

On the Fuzzy Number Space with the Level Convergence Topology
Journal of Function Spaces, Volume 2012, Issue 1, 2012., 2012 We characterize compact sets of 𝔼1 endowed with the level convergence topology τℓ. We also describe the completion (𝔼1∧,𝒰∧) of 𝔼1 with respect to its natural uniformity, that is, the pointwise uniformity 𝒰, and show other topological properties of 𝔼1∧, as separability.

Proto-metrizable fuzzy topological spaces [PDF]
, 1999 summary:In this paper we define for fuzzy topological spaces a notion corresponding to proto-metrizable topological spaces. We obtain some properties of these fuzzy topological spaces, particularly we give relations with non-archimedean, and metrizable ...

Local homogeneity in fuzzy topological spaces
International Journal of Mathematics and Mathematical Sciences, Volume 2006, Issue 1, 2006., 2006 Three types of local homogeneity in L‐topological spaces are introduced and studied, and each is characterized and proved to be a good extension of local homogeneity in ordinary topological spaces. Many implications concerning them are introduced. The study deals with the L‐topologically generated topological spaces.

Finite-to-one fuzzy maps and fuzzy perfect maps [PDF]
, 1982 summary:In this paper we define, for fuzzy topology, notions corresponding to finite-to-one and $k$-to-one maps. We study the relationship between these new fuzzy maps and various kinds of fuzzy perfect maps.
