I'll report on recent applications of the LLL to two problems in the dynamics of general countable groups. The first concerns the existence of free symbolic minimal actions; the second asks about realizations of URS's (uniformly recurrent subgroups) as stability systems.
I'll then concentrate on a solution of Gabor Elek to the second problem in the case of finitely generated groups.
