Convergences in fuzzy topological spaces

Fuzzy Sets and Systems, 1999
The authors introduce and investigate the notions of fuzzy upper limit, fuzzy lower limit and fuzzy limit of a net of fuzzy subsets of a fuzzy topological space in terms of quasi neighbourhoods, generalize Kuratowski's notion of continuous convergence to the set of fuzzy continuous functions and characterize fuzzy compactness and fuzzy continuous ...

Fuzzy soft topological spaces

Journal of Intelligent & Fuzzy Systems, 2017
Fuzzy soft topological space was introduced and studied by B. Tanay et al. [ 8 ]. This paper introduces fuzzy soft point and study the concept of neighborhood of a fuzzy soft point in a fuzzy soft topological space alongwith the study of fuzzy soft closure and fuzzy soft interior.

The fuzzy topological spaces on a fuzzy space

Fuzzy Sets and Systems, 1999
The author proposes a definition of fuzzy topology. In this definition a notion of fuzzy topology is considered on a fuzzy subspace [\textit{K. A. Dib}, Inf. Sci. 80, No. 3-4, 253-282 (1994; Zbl 0832.20088)] as a collection of fuzzy subspaces satisfying conditions similar to Chang-fuzzy topology [\textit{C. L. Chang}, J. Math. Anal. Appl.

On intuitionistic fuzzy topological spaces

Kybernetes, 2006
PurposeIn 2000, Wang and He published an important result on the theory of intuitionistic fuzzy sets (IFSs). Indeed, they showed that every IFS may be regarded as an L‐fuzzy set for some appropriate lattice L. This paper aims to show that, nevertheless, the results obtained by various authors on intuitionistic fuzzy topological spaces (IFTSs), are not ...

Quotient fuzzy topological spaces

Fuzzy Sets and Systems, 2001
The author proves that a continuous function \(f\) which maps a topological space \((X,\tau)\) to another topological space \((Y,\eta)\) is a quotient map if and only if \(f:(X,\omega(\tau))\to (Y,\omega (\eta))\) is a quotient map, where \(\omega\) denotes the Lowen functor from the category of topological spaces to that of fuzzy topological spaces ...

Connectedness in -fuzzy topological spaces

Fuzzy Sets and Systems, 2000
Let \(L\) be a completely distributive lattice with an order-reversing involution and \((L^X, \delta)\) be an \(L\)-topological space, that is, \(\delta\) is a subset of \(L^X\) closed under finite infs and arbitrary sups. For each prime \(a\in L\), \(\iota_a(\delta) = \{\iota_a(\lambda) \mid \lambda\in\delta\}\) is a topology on \(X\), called the \(a\)
