Fuzzy normal subgroups and fuzzy cosets

Information Sciences, 1984
The concept of fuzzy subgroup [cf. \textit{A. Rosenfeld}, J. Math. Anal. Appl. 35, 512-517 (1971; Zbl 0194.055); \textit{P. S. Das}, J. Math. Anal. Appl. 84, 264-269 (1981; Zbl 0476.20002)] is investigated. Several (fuzzy type) extensions of known results for normal subgroups, quotient groups and finite groups are obtained.

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.

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

Fuzzy congruences and fuzzy normal subgroups

Information Sciences, 1992
The paper deals with fuzzy congruences on a group [cf. \textit{P. Bhattacharya} and \textit{N. P. Mukherjee}, ibid. 36, 267-282 (1985; Zbl 0599.20003)] and states a one-to-one correspondence between them and normal fuzzy subgroups (which is analogous to the group case). A similar result was recently presented by \textit{B. B.

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.
