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 subgroups and anti fuzzy subgroups

Fuzzy Sets and Systems, 1990
Using de Morgan's laws in the calculus of fuzzy sets the author discusses notions dual to level sets of fuzzy sets and to fuzzy groups [cf. \textit{P. S. Das}, J. Math. Anal. Appl. 84, 264-269 (1981; Zbl 0476.20002)]. The de Morgan complement of a fuzzy group is called here ``anti fuzzy group'' (without any algebraic analogy).

Fuzzy subgroups of n-ary subgroups

Journal of Mathematical Sciences, 2012
The first fuzzification of an \(n\)-ary algebraic structure was introduced in 2000 by \textit{W. A. Dudek} [Quasigroups Relat. Syst. 7, 45-66 (2000; Zbl 0986.20069)]. The notion of intuitionistic fuzzy set in \(n\)-ary systems was defined and studied also by \textit{W. A. Dudek} [ibid. 13, No. 2, 213-228 (2005; Zbl 1109.20059)].
