Abstract: We prove that the intersection of all maximal special-valued subgroups of a lattice-ordered group is the special-valued quasi-torsion radical of a lattice-ordered group , which extends our earlier result that the intersection of all maximal finite-valued subgroups of a lattice-ordered group is the finite-valued torsion radical of . We also show that the class of almost finite-valued lattice-ordered groups is a quasi-torsion class, and the quasi-torsion radical of a group is equal to the intersection of the group with the lateral completion of the finite-valued torsion radical of the group.
