In this paper, by considering the notions of polygroup and Engel group, we introduce the concept of Engel fuzzy subpolygroups. In this regard, by a normal Engel fuzzy subpolygroup μμ of PP and β*β∗, the fundamental relation on a given polygroup PP, we construct an Engel fuzzy subgroup μβ*μβ∗. We obtain a necessary and sufficient condition between Engel fuzzy subpolygroups and the Engel group PP/∼∼, the group of equivalence classes derived from a fuzzy subpolygroup of PP. Finally, by using these results, we get Zorn’s lemma, in the Engel fuzzy subpolygroups.
