Pro-p groups acting on trees with finitely many maximal vertex stabilizers up to conjugation
Zoé Chatzidakis, Pavel Zalesskii
We prove that a finitely generated pro- group acting on a pro- tree splits as a free amalgamated pro- product or a pro- HNN-extension over an edge stabilizer. I…

A note on the non-existence of prime models of theories of pseudo-finite fields
Zoé Chatzidakis
We show that if a field A is not pseudo-finite, then there is no prime model of the theory of pseudo-finite fields over A. Assuming GCH, we generalise this result to κ-prime models…

Remarks around the non-existence of difference-closure
Zoé Chatzidakis
This paper shows that in general, difference fields do not have a difference closure. However, we introduce a stronger notion of closure (kappa-closure), and show that every algebr…
