Seminarium KMMF "Teoria Dwoistości"

We will start by reviewing the definition and fundamental properties of Sasakian manifolds compared with the Kaehler case. Later on, we will describe their topological properties, emphasizing our contribution about the Hard Lefschetz Theorem and Sasakian nilmanifolds. The latter will require a brief review of the concept of formality and Sullivan model of a graded commutative differential algebra.
