Model theory of fields with free operators in characteristic zero
E-mail:

Submission date: 23 December 2012.

Abstract:

Generalising and unifying the known theorems for difference and differential fields, it is shown that for every finite free S-algebra D over a field A of characteristic zero the theory of D-fields has a model companion D-CF_0 which is simple and satisfies the Zilber dichotomy for finite-dimensional minimal types.
