Abstract
We study cyclic elements of order n of GMV-algebras. The existence of cyclic elements is equivalent to the condition that a given GMV-algebra contains a copy of the MV-algebra \(\Upgamma({\mathbb Z},n).\) Using cyclic elements, we describe necessary conditions which guarantee the existence of a greatest subalgebra belonging to the variety generated by \(\Upgamma({\mathbb Z},n).\) This is true, e.g. for representable GMV-algebras. Finally, we use cyclic elements to prove the existence of a free product in various varieties of GMV-algebras.
