Abstract

The present paper is a sequel to Paoli F, Ledda A, Giuntini R,Freytes H (On some properties of QMV algebras and √' QMValgebras, submitted). We provide two representation results forquasi-MV algebras in terms of MV algebras enriched with additionalstructure; we investigate the lattices of subvarieties andsubquasivarieties of quasi-MV algebras; we show that quasi-MValgebras, as well as cartesian and flat √' quasi-MV algebras,have the amalgamation property.
