Abstract

top
In this article, it will be shown that every ℓ -subgroup of a Specker ℓ -group has singular elements and that the class of ℓ -groups that are ℓ -subgroups of Specker ℓ -group form a torsion class. Methods of adjoining units and bases to Specker ℓ -groups are then studied with respect to the generalized Boolean algebra of singular elements, as is the strongly projectable hull of a Specker ℓ -group.
