710. Quentin Brouette and Francoise Point
Differential Galois Theory in the class of formally real fields
E-mail:

Submission date: 13 April 2014.

Abstract:

We study strongly normal extensions within the class of formally real fields. Assuming that the constant field is real closed, we show that the differential Galois groups are semi-algebraic. We prove a partial Galois correspondence.
