DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGOON/88/">
 Non-commutative abelian surfaces and generalized Kummer varieties</a>\nby 
 Laura Pertusi (University of Milano\, Italy) as part of Longitudinal Algeb
 ra and Geometry Open ONline Seminar (LAGOON)\n\n\nAbstract\nA hyperkaehler
  manifold is a compact complex simply connected Kaehler manifold whose spa
 ce of holomorphic two-forms is generated by a symplectic form\, unique up 
 to scalar multiplication. Together with complex tori and irreducible Calab
 i--Yau manifolds\, they are building blocks for compact Kaehler manifolds 
 with trivial first Chern class. In dimension two hyperkaehler manifolds ar
 e K3 surfaces\, while finding examples in higher dimensions is a challengi
 ng problem. In this talk we will construct new families of hyperkahler man
 ifolds of generalized Kummer type via moduli spaces of stable objects in a
  noncommutative deformation of the bounded derived category of an abelian 
 surface. This work in progress is joint with Arend Bayer\, Alex Perry and 
 Xiaolei Zhao.\n\nhttps://uni-koeln.zoom.us/j/91875528987?pwd=US8wdjNrWjl5d
