Abelian l-groups with strong unit and perfect MV-algebras

By L.P. Belluce, A. Di Nola, B. Gerla We investigate the class of abelian l-groups with strong unit corresponding to perfect MV-algebras via the Gamma functor, showing that this is a universal subclass of the class of all abelian l-groups Read more…

A discrete representation of free MV-algebras

by A. Di Nola, R. Grigolia and L. Spada It is proved that the n-generated free MV-algebra is isomorphic to a quotient of the disjoint union of all the n-generated free MVn-algebras. Such a quotient can be seen as the Read more…

Embeddings of totally ordered MV-algebras of bounded cardinality

by Piotr Wojciechoski For a given cardinal number a, we construct a totally ordered MV-algebra M(a) having the property that every totally-ordered MV-algebra of cardinality at most a embeds into M(a). In case a = ℵ0 , the algebra M(a) Read more…

“MV algebras from the point of view of o-minimality” Abstract: O-minimality is a model-theoretic concept for ordered structures that amountsto requiring definable sets over the domain to be a finite union of singletons and open intervals.In this very informal talk, Read more…
