Corps différentiels et Flots géodésiques I : Un critère dynamique d'orthogonalité aux constantes pour les D-variétés réelles

Submission date: 19 December 2016


We present a criterion of orthogonality to the constants for absolutely irreducible real D-varieties relying on the topological dynamic of the associated real analytic flow. More precisely, we prove that if there exists Zariski-dense invariant compact region of the smooth locus of real points of X where the dynamic of the real analytic flow is topologically weakly mixing, then the generic type of (X,v) is orthogonal to the constants. This criterion will be applied in a second part of this article to the model-theoretic study of the geodesic flow of compact real algebraic Riemannian manifolds with negative curvature.
