Simplicity of the automorphism group of fields with operators

Logic 2025-04-07 v4 Group Theory

Abstract

We adapt a proof of Lascar in order to show the simplicity of the group of automorphisms fixing pointwise all non-generic elements for a class of uncountable models of suitable theories, encompassing both strongly minimal theories as well as several theories of fields with operators.
