Abstract
An explicit categorical equivalence is defined between a proper subvariety of the class of \({ PMV}\)-algebras, as defined by Di Nola and Dvurečenskij, to be called \({ PMV}_{f}\)-algebras, and the category of semi-low \(f_u\)-rings. This categorical representation is done using the prime spectrum of the \({ MV}\)-algebras, through the equivalence between \({ MV}\)-algebras and \(l_u\)-groups established by Mundici, from the perspective of the Dubuc–Poveda approach, that extends the construction defined by Chang on chains. As a particular case, semi-low \(f_u\)-rings associated to Boolean algebras are characterized.
