SUMMARY:Seminar Algebra and Geometry: Wendelin Lutz (Universität Hannover)
DESCRIPTION:Let Y be a Calabi—Yau variety. The Morrison Cone Conjecture i
 s a fundamental conjecture in Algebraic Geometry on the geometry of the ne
 f cone and the movable cone of Y: while these cones are usually not ration
 al polyhedral\, the cone conjecture predicts that the action of Aut(Y) on 
 Nef(Y) admits a rational polyhedral fundamental domain\, and that the acti
 on of Bir(Y) on Mov(Y) admits a rational polyhedral fundamental domain. Ev
 en though the conjecture has been settled in special cases\, it is still w
 ide open in dimension at least 3. We prove that if the cone conjecture hol
 ds for a smooth Calabi-Yau threefold Y\, then it also holds for any smooth
  deformation of Y.  If time permits\, I will explain how to generalize so
 me of the ideas to the case of log Calabi-Yau varieties.
