[Invariants des variétés symplectiques rationnelles réelles de dimension quatre, et bornes inférieures en géométrie énumérative réelle]
Suivant l'approche de Gromov et Witten, nous construisons des invariants par déformation des variétés symplectiques réelles rationnelles de dimension quatre. Ces invariants fournissent des bornes inférieures pour le nombre de courbes J-holomorphes rationnelles réelles de classe d'homologie donnée passant par une configuration réelle de points donnée.
Following the approach of Gromov and Witten, we construct invariants under deformation of real rational symplectic 4-manifolds. These invariants provide lower bounds for the number of real rational J-holomorphic curves in a given homology class passing through a given real configuration of points.
