The smoothness conjecture for invariant generically stable measures in n-distal groups

Less than 1 year old · traced to

Assume 2≤k∈ω2\leq k\in\omega, let TT be a kk-distal NIP theory, and let GG be a definable group. Let μ∈MG(M)\mu\in\mathfrak{M}_{G}(\mathbb{M}) be a generically stable, GG-invariant measure. Smoothness conjecture. The measure μ\mu is smooth. In particular, if GG is fsg, then GG is compactly dominated. More generally, the analogous question can be asked for fim groups in not necessarily NIP kk-distal theories. Smoothness of such measures would extend the known distal result and yield compact domination and its arithmetic regularity consequences in the broader kk-distal setting; the source does not indicate a resolution.
