Interests
I am interested in pure model theory and its connections with algebra and topology, particularly in:- topological dynamics methods in model theory
- Lascar strong types, Galois groups, and spaces of strong types,
- profinite structures, profinite groups and rings regarded as profinite structures,
- Polish structures, Polish [compact] $G$-groups,
- stable, simple, rosy and NIP theories, groups and fields,
- $\omega$-categorical groups and rings,
- minimal and quasi-minimal structures.
