A characterisation of lattice-ordered abelian groups.
A completion for partially ordered abelian groups.
A constructive proof that every 3-generated l-group is ultrasimplicial
We discuss the ultrasimplicial property of lattice-ordered abelian groups and their associated MV-algebras. We give a constructive proof of the fact that every lattice-ordered abelian group generated by three elements is ultrasimplicial.

Additive closure operators on abelian unital -groups
In the paper an additive closure operator on an abelian unital -group is introduced and one studies the mutual relation of such operators and of additive closure ones on the -algebra .
Affine completeness and lexicographic product decompositions of abelian lattice ordered groups
In this paper it is proved that an abelian lattice ordered group which can be expressed as a nontrivial lexicographic product is never affine complete.
Affine completness of projectable lattice ordered groups
Algebraic Classes of Abelian Torsion-Free and Lattice-Ordered Groups
Algebre di Łukasiewicz quasi-locali Stoneane
We prove some properties of quasi-local Ł-algebras. These properties allow us to give a structure theorem for Stonean quasi-local Ł-algebras. With this characterization we are able to exhibit an example which provides a negative answer to the first problem posed in [4].
Archimedean kernel of a lattice ordered group
Archimedean unital groups with finite unit intervals.
