Sur la dynamique des difféomorphismes birationnels des surfaces algébriques réelles : ensemble de Fatou et lieu réel

Abstract

This text deals with birationnal diffeomorphisms of real algebraic surfaces which have simple real dynamics and rich complex dynamics. We give an example of such a transformation on P^1xP^1, then we show that this situation is exceptional and implies strong conditions on both the topology of the real locus and the real dynamics.
