Model Theory of Groups Actions on Fields: Revisited

Özlem Beyarslan
(T.C. Boğaziçi Üniversitesi)
Abstract
We revisit the model theory of fields with a group action by automorphisms, focusing on the existence of the model companion G-TCF. We explain a flaw in earlier work and present the corrected result: for finitely generated virtually-free groups G, G-TCF exists if and only if G is finite or free. This is joint work with Piotr Kowalski.
