196. Ronald F. Bustamante Medina
Model Theory of Differentially Closed Fields with a Generic Automorphism
E-mail:

Submission date: 28 July 2009.

Abstract:

E. Hrushovski proved that the theory of difference-differential fields has a model companion. We prove this result and other main properties of this theory that we call DCFA. We describe the SU rank and its relation with transcendence degree. We prove a version of Zilber's dichotomy and we give a description of Abelian definable groups. (This part of the author's PhD thesis).
