Definable groups in topological fields with a generic derivation
Francoise Point
We continue the study of a class of topological -fields endowed with a generic derivation , focussing on describing definable groups. We show that one can associate…

Embedded Picard-Vessiot extensions
Quentin Brouette, Greg Cousins, Anand Pillay +1
We prove that if T is a theory of large, bounded, fields of characteristic zero, with almost quantifier elimination, and T_D is the model companion of T + "D is a derivation", then…

The Ziegler spectrum of the ring of entire complex valued functions
Sonia L'Innocente, Francoise Point, Gena Puninski +1
We will describe the Ziegler spectrum of the ring of entire complex valued functions
