An Isaac Newton Institute Workshop

Model Theory, Algebraic and Analytic Geometry

Model theory of difference fields and some remarks on Galois groups.

Author: Z Chatzidakis (CNRS - Universite Paris 7)

Abstract

In this talk I will present a short survey of the results known to-date on generic difference fields. I will also discuss Galois groups of difference equations, and why the model-theoretic Galois group coincides with the classical Galois group defined using Picard-Vessiot extensions
