On donne un exemple d’une variété symplectique compacte de dimension qui n’admet aucune structure Kählerienne, mais qui satisfait la condition de Lefschetz Forte et dont l’algèbre de DeRham est formelle ; de plus, on montre que peut être dotée d’une structure de Calabi-Yau généralisée spéciale.
We give an example of a compact 6-dimensional non-Kähler symplectic manifold that satisfies the Hard Lefschetz Condition. Moreover, it is showed that is a special generalized Calabi-Yau manifold.
