Dynamics lunch: Tom Gilat (HUJI) - Finding almost-periods of convolutions in the context of additive combinatorics (following Croot and Sisask)

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.
