Resumen de On varieties of MV-algebras with internal states

Antonio Di Nola, Anatolij Dvurecenskij, Ada Lettieri

• In [4] and [5] the authors introduced the variety of MV-algebras with an internal operator, state MV-algebras. In [2] and [3] the authors gave a stronger version of state MV-algebras, called state-morphism MV-algebras. In this paper we continue the studies presented in [2] and [3] just looking at several proper subvarieties of , obtained by imposing suitable conditions on the behavior of the internal operator.
