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

Chatzidakis, Z *(Paris 7)*

Friday 15 July 2005, 09:00-10:00

Seminar Room 1, Newton Institute

#### 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
