Locally $ℵ_{0}$ -categorical theories and locally Roelcke precompact groups

Itaï Ben Yaacov, Todor Tsankov

It is well-known that Polish Roelcke precompact groups are the groups that can be represented as automorphism groups of $ℵ_{0}$ -categorical structures in continuous logic and th…

Dense and comeager conjugacy classes in zero-dimensional dynamics

Michal Doucha, Julien Melleray, Todor Tsankov

Given a countable group $G$ , we initiate a systematic study of the Polish spaces of all minimal and topologically transitive actions of $G$ on the Cantor space by homeomorphisms, w…

Non-singular and probability measure-preserving actions of infinite permutation groups

Todor Tsankov

We prove two theorems in the ergodic theory of infinite permutation groups. First, generalizing a theorem of Nessonov for the infinite symmetric group, we show that every non-singu…

Extremal models and direct integrals in affine logic

Itaï Ben Yaacov, Tomás Ibarlucía, Todor Tsankov

Affine logic is a fragment of continuous logic, introduced by Bagheri, in which only affine functions are allowed as connectives. This has the effect of endowing type spaces with t…

Continuity of the stabilizer map and irreducible extensions

Adrien Le Boudec, Todor Tsankov

Let $G$ be a locally compact group. For every $G$ -flow $X$ , one can consider the stabilizer map $x \mapsto G_{x}$ , from $X$ to the space $Sub (G)$ of closed subgroups of $G$ .…

On compact uniformly recurrent subgroups

Pierre-Emmanuel Caprace, Gil Goffer, Waltraud Lederle +1

Let a group $Γ$ act on a paracompact, locally compact, Hausdorff space $M$ by homeomorphisms and let $2^{M}$ denote the set of closed subsets of $M$ . We endow $2^{M}$ with the Chabauty…
