Fuzzy subgroups: Some characterizations
Journal of Mathematical Analysis and Applications, 1987 The author considers fuzzy groups on a finite group and examines an equivalence relation between them: possession of the same family of level subgroups. The paper gives some refinements of results and proofs of \textit{P. S. Das} [J. Math. Anal. Appl. 84, 264--269 (1981; Zbl 0476.20002)]. This paper was continued [cf. Part II, Inf. Sci.

Pinned-flags of some operations on fuzzy subgroups
International Journal of Mathematics and Mathematical Sciences, 2005 Fuzzy subgroups of finite groups have been treated recently using the concept of pinned-flags. In this paper, we consider the operations of intersection, sum, product, and quotient of fuzzy subgroups of finite abelian groups in general, in terms of ...

FUZZY SUBGROUPS BASED ON FUZZY POINTS [PDF]
Communications of the Korean Mathematical Society, 2011 Using the "belongs to" relation and "quasi-coincident with" relation between a fuzzy point and a fuzzy subgroup, Bhakat and Das, in 1992 and 1996, initiated general types of fuzzy subgroups which are a generalization of Rosenfeld's fuzzy subgroups. In this paper, more general notions of "belongs to" and "quasi-coincident with" relation between a fuzzy ...

Monopoles and Solitons in Fuzzy Physics
, 1999 Monopoles and solitons have important topological aspects like quantized fluxes, winding numbers and curved target spaces. Naive discretizations which substitute a lattice of points for the underlying manifolds are incapable of retaining these features ...

Generalized Complex Fuzzy and Anti-Fuzzy H_v-Subgroups
International Journal of Analysis and Applications, 2018 In this paper, we introduce the concept of generalized complex fuzzy subhypergroup ($H_{v}$-subgroup) as well as the generalized concept of complex anti-fuzzy subhypergroup ($H_{v}$-subgroup).

On Structural Properties of ξ-Complex Fuzzy Sets and Their Applications
Complexity, 2020 Complex fuzzy sets are the novel extension of Zadeh’s fuzzy sets. In this paper, we comprise the introduction to the concept of ξ-complex fuzzy sets and proofs of their various set theoretical properties. We define the notion of α,δ-cut sets of ξ-complex
