Hypersurfaces Symplectiques Réelles et Pinceaux de Lefschetz Réels
In a compact symplectic real manifold, i.e., supporting an antisymplectic involution, we use Donaldson's construction to build a codimension 2 symplectic submanifold invariant under the action of the involution.If the real part of the manifold is not empty, and if the symplectic form ω is entire, then there is an …
