*Laura Pertusi  (University of Milano)  Non-commutative abelian surfaces
and generalized Kummer varieties *
Abstract. A hyperkähler manifold is a compact complex simply connected
Kähler manifold whose space of holomorphic two-forms is generated by a
symplectic form, unique up to scalar multiplication. Together with complex
tori and irreducible Calabi–Yau manifolds, they are building blocks for
compact Kähler manifolds with trivial first Chern class. In dimension two
hyperkähler manifolds are K3 surfaces, while finding examples in higher
dimensions is a challenging problem. In this talk we will construct new
families of hyperkähler manifolds of generalized Kummer type via moduli
spaces of stable objects in a non-commutative deformation of the bounded
derived category of an abelian surface. This work in progress is joint with
Arend Bayer, Alex Perry and Xiaolei Zhao.
