Abstract.
The Bott-Chern and the Aeppli cohomology groups provide useful global tools in studying non-Kähler geometry. We will recall their denitions and properties, studied by L.-S. Tseng and S.-T. Yau, on compact symplectic manifolds and then we will discuss their generalization to locally conformally symplectic manifolds. In both cases we will discuss the notion of Hard-Lefschetz condition in relation with the dδ-lemma. These are joint works with Daniele Angella, Alexandra Otiman and Adriano Tomassini.
