Dans cet article nous étudions la structure de l’ensemble des points faiblement produit-récurrents. Nous donnons entre autres des conditions suffisantes (en rapport avec le mélange topologique faible) qui impliquent que l’ensemble des points faiblement produit-récurrents est résiduel. De plus, nous obtenons certains résultats nouveaux concernant la classe des systèmes disjoints de tous les systèmes minimaux.

In this article we study the structure of the set of weakly product recurrent points. Among others, we provide necessary conditions (related to topological weak mixing) which imply that the set of weakly product recurrent points is residual. Additionally, some new results about the class of systems disjoint from every minimal system are obtained.
