Fuzzy cosets and fuzzy normal subgroups

Information Sciences, 1992
The paper discusses properties of fuzzy normal groups (e.g. homomorphic images). The manuscript of the paper is from 1987 (``sup property'' is assumed!). Current results and recent literature can be found in the paper by \textit{I. J. Kumar, P. K. Saxena} and \textit{P. Yadav} [Fuzzy Sets Syst. 46, 121-132 (1992; Zbl 0776.20025)].

Normal fuzzy -subgroups in near-rings

Fuzzy Sets and Systems, 2001
The authors define and study normal fuzzy \(R\)-subgroups in near-rings, that is, systems whose addition is a group, whose multiplication is a semigroup, having a one-sided distributive law.

The normal intuitionistic fuzzy subgroups

2010 IEEE International Conference on Intelligent Computing and Intelligent Systems, 2010
In this paper,we present the concept of (α, β)-normal intuitionistic fuzzy subgroup. And we show that, in 16 kinds of (α, β)-normal intuitionistic fuzzy subgrous, the significant ones are the (∈,∈)-normal intuitionistic fuzzy subgroup, the (∈, ∈ ∨q)- normal intuitionistic fuzzy subgroup and the (∈ ∧q, ∈)- normal intuitionistic fuzzy subgroup.

Homomorphisms and fuzzy (fuzzy normal) subgroups

Fuzzy Sets and Systems, 1991
By using the idea of a level subgroup of a fuzzy subgroup a different proof of Theorem 1 of Eroglu is given. Also a generalization of Theorem 3.9 of Mukherjee and Bhattacharya is made by dropping the assumption that the group \(G\) is finite.

The lattices of normal intuitionistic fuzzy subgroups

Proceedings. International Conference on Machine Learning and Cybernetics, 2003
In this paper, we discuss the sublattices of intuitionistic fuzzy subgroups of a given group and some special sublattices corresponding to it. We prove that a class of intuitionistic fuzzy normal subgroups constitutes a modular of the lattice of intuitionistic fuzzy normal subgroups.

A new type of fuzzy normal subgroups and fuzzy cosets

Journal of Intelligent & Fuzzy Systems, 2013
Using the notions of belonging (∈) and quasi-k-coincidence (q k ) of a fuzzy point with a fuzzy set, we define the concepts of $(\overline{\in}, \overline{\in} \vee \overline{q_{k}})$-fuzzy normal subgroups and $(\overline{\in }, \overline{\in } \vee \overline{q_{k}})$-fuzzy cosets which is a
