Abstract
Résumé

We present an existence theorem for Picard–Vessiot extensions over real differential fields with real closed field of constants.

Nous donnons un théorème dʼexistence pour des extensions de type Picard–Vessiot sur un corps différentiel réel dont le corps des constantes est réel clos.
