Differential Galois Theory in the class of formally real fields
Submission date: 13 April 2014.
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.
