Abstract

In this paper, we study an equivalence relation on the set of fuzzy
subgroups of an arbitrary group G and give four equivalent conditions each of
which characterizes this relation. We demonstrate that with this equivalence
relation each equivalence class constitutes a lattice under the ordering of fuzzy set
inclusion. Moreover, we study the behavior of these equivalence classes under the
action of a group homomorphism.
