Özlem Beyarslan, Daniel Max Hoffmann, Moshe Kamensky +1
We give algebraic conditions about a finite algebra over a perfect field of positive characteristic, which are equivalent to the companionability of the theory of fields with "…

On Galois groups and PAC substructures
Daniel Max Hoffmann
We show that for an arbitrary stable theory T, a group G is profinite if and only if G occurs as a Galois group of some Galois extension inside a monster model of T. We prove that…
