Scott convergence and fuzzy Scott topology on L-posets

open access: yesOpen Mathematics, 2017
We firstly generalize the fuzzy way-below relation on an L-poset, and consider its continuity by means of this relation. After that, we introduce a kind of stratified L-generalized convergence structure on an L-poset.

Fuzzy T1-topological spaces

open access: yesJournal of Mathematical Analysis and Applications, 1984
The authors define fuzzy \(T_ 1\)-topological spaces (X,\(\tau)\) using fuzzy points introduced by \textit{C. K. Wong} [ibid. 46, 316-328 (1974; Zbl 0278.54004)]. \(T_ 1\)-ness is defined as weak separation by fuzzy open sets. The main theorem shows a difference to the topological analogue.

Application of Induced Preorderings in Score Function-Based Method for Solving Decision-Making with Interval-Valued Fuzzy Soft Information

open access: yesMathematics, 2021
Ranking interval-valued fuzzy soft sets is an increasingly important research issue in decision making, and provides support for decision makers in order to select the optimal alternative under an uncertain environment.

Weak fuzzy topology on fuzzy topological vector spaces

open access: yes, 2019
In this paper, we introduce the concept of weak fuzzy linear topology on a fuzzy topological vector space as a generalization of usual weak topology. We prove that this topology consists of all weakly lower semi-continuous fuzzy sets on a given vector space when K (R or C) considered with its usual fuzzy topology.

Relationship of Algebraic Theories to Powerset Theories and Fuzzy Topological Theories for Lattice-Valued Mathematics

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
This paper deals with a broad question—to what extent is topology algebraic—using two specific questions: (1) what are the algebraic conditions on the underlying membership lattices which insure that categories for topology and fuzzy topology are indeed ...

On some applications of fuzzy points

open access: yesApplied General Topology, 2005
The notion of preopen sets play a very important role in General Topology and Fuzzy Topology. Preopen sets are also called nearly open and locally dense.

Fuzzy properties in fuzzy convergence spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
Based on the concept of limit of prefilters and residual implication, several notions in fuzzy topology are fuzzyfied in the sense that, for each notion, the degree to which it is fulfilled is considered.

Intuitionistic fuzzy proximity spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We introduce the concept of the intuitionistic fuzzy proximity as a generalization of fuzzy proximity, and investigate its properties. Also we investigate the relationship among intuitionistic fuzzy proximity and fuzzy proximity, and intuitionistic fuzzy

Fuzzy r-continuous and fuzzy r-semicontinuous maps

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 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 ...

Fuzzy topology and fuzzy multifunctions

open access: yesJournal of Mathematical Analysis and Applications, 1985
Some fuzzy topological concepts (F-dense and F-nowhere dense sets, F- boundary, regular f.t.s. and others) are introduced and studied. Some of the results are as follows. If \((X,\tau_ X)\) and \((Y,\tau_ Y)\) are f.t.s. then F-boundary sets are stable under F-continuous surjections \(f: X\to Y\); if in addition f is F-closed then the family of F ...
