Using Taubes' results, we prove that on a symplectic almost complex manifold with an antisymplectic and antiholomorphic involution, this invariants are not all trivial, and that the canonical bundle is represented by a real holomorphic curve.In frenchDifferential GeometryComplex VariablesSymplectic Geometry14P25, 53D05, 57R57text
