Model theory of fields with free operators in positive characteristic

Logic 2019-05-16 v3

Abstract

We give algebraic conditions about a finite algebra BB over a perfect field of positive characteristic, which are equivalent to the companionability of the theory of fields with "BB-operators" (i.e. the operators coming from homomorphisms into tensor products with BB). We show that, in the most interesting case of a local BB, these model companions admit quantifier elimination in the "smallest possible" language and they are strictly stable. We also describe the forking relation there.
