Abstract: In this paper we prove that the system of all closed convex $\ell$-subgroups of a convergence $\ell$-group is a Brouwer lattice and that a similar result is valid for radical classes of convergence $\ell$-groups.

Keywords: convergence $\ell$-group, closed convex $\ell$-subgroup, radical class of convergence $\ell$-groups
