The lattices of fuzzy subgroups and fuzzy normal subgroups

Information Sciences, 1994
The paper deals with fuzzy subgroups and fuzzy normal subgroups of a given group [cf. \textit{I. J. Kumar, P. K. Saxena, P. Yadav}, Fuzzy Sets Syst. 46, 121-132 (1992; Zbl 0776.20025)]. The main result of this paper is a special case of Theorem 3.8 and Remark 3.9 of \textit{M. Mashinchi, Sh. Salili, M. M. Zahedi} [Bull. Iran. Math. Soc. 18, 17-29 (1992;

Fuzzy normal subgroups and fuzzy quotients

Fuzzy Sets and Systems, 1992
The paper brings a valuable comparison of different approaches to the consideration of fuzzy normal subgroups and fuzzy quotients. After the presentation of recent results we get new definitions and theorems with suitable counterexamples. The last part of the paper deals with direct products of fuzzy subgroups.

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.

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.
