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.

A Note on Fixed Fuzzy Points for Fuzzy Mappings [PDF]
, 2001 We prove a fixed fuzzy point theorem for fuzzy contraction mappings (in the S. Heilpern’s sense) over a complete metric space, and as a consequence we obtain a fixed point theorem in the context of intuitionistic fuzzy ...

International Journal of Mathematics and Mathematical Sciences, Volume 22, Issue 4, Page 727-737, 1999., 1999 In [3], we started the investigation of compactness in fuzzy function spaces in FCS, the category of fuzzy convergence spaces as defined by Lowen/Lowen/Wuyts [8]. This paper goes somewhat deeper in the investigation of fuzzy function spaces using the notion of splitting and conjoining structures on fuzzy subsets.

A Pseudo-Measure of Fuzziness [PDF]
, 2001 In this note we give an example of a gradationof openness (a fuzzy topology in Shostak’s sense) and deduce from it a pseudo-measure of ...

Common fixed point theorems and applications [PDF]
, 1997 The purpose of this paper is to discuss the existence of common fixed points for mappings in general quasi-metric spaces. As applications, some common fixed point theorems for mappings in probabilistic quasi-metric spaces are given. The results presented

Fuzziness in Chang's fuzzy topological spaces [PDF]
, 1999 It is known that fuzziness within the concept of openness of a fuzzy set in a Chang's fuzzy topological space (fts) is absent. In this paper we introduce a gradation of openness for the open sets of a Chang jts (X, $\mathcal{T}$) by means of a map ...

On fuzzy phi-contractive sequences and fixed point theorems [PDF]
, 2016 In this paper we give a fixed point theorem in the context of fuzzy metric spaces in the sense of George and Veeramani. As a consequence of our result we obtain a fixed point theorem due to D.

A fixed point theorem for fuzzy contraction mappings [PDF]
, 1999 In this paper, we give a fixed point theorem for fuzzy contraction mappings in quasi-pseudo-metric spaces which is a generalization of the corresponding one for metric spaces given by S ...

C# Application to Deal with Neutrosophic g(alpha)-Closed Sets In Neutrosophic Topology [PDF]
, 2020 In this paper, we have developed a C# Application for finding the values of the complement, union, intersection and the inclusion of any two neutrosophic sets in the neutrosophic field by using .NET Framework, Microsoft Visual Studio and C# Programming ...

On the uniformization of L-valued frames [PDF]
, 1994 This note discusses the appropriate way of uniformizing the notion of an L-valued frame introduced by A. Pultr and S. Rodabaugh in [Lattice-valued frames, functor categories, and classes of sober spaces, Chapter 6 of Topological and Algebraic ...
