Hereditary G-compactness

Tomasz Rzepecki

We introduce the notion of hereditary G-compactness (with respect to interpretation). We provide a sufficient condition for a poset to not be hereditarily G-compact, which we use t…

Bounded Invariant Equivalence Relations

Tomasz Rzepecki

We study strong types and Galois groups in model theory from a topological and descriptive-set-theoretical point of view, leaning heavily on topological dynamical tools. More preci…

Galois groups as quotients of Polish groups

Krzysztof Krupiński, Tomasz Rzepecki

We present the (Lascar) Galois group of any countable theory as a quotient of a compact Polish group by an $F_{σ}$ normal subgroup: in general, as a topological group, and under NIP,…
