DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ZAG/148/">Se
 rre functors of semiorthogonal components</a>\nby Alexander Perry (Univers
 ity of Michigan) as part of ZAG (Zoom Algebraic Geometry) seminar\n\n\nAbs
 tract\nThe Serre functor of a triangulated category is one of its most imp
 ortant invariants\, playing the role of the dualizing complex of a variety
  in noncommutative algebraic geometry. I will explain how to describe the 
 Serre functors of many semiorthogonal components of varieties in terms of 
 spherical twists. In the case of Kuznetsov components of Fano complete int
 ersections\, this leads to a proof of a conjecture of Katzarkov and Kontse
 vich on the dimensions of such categories\, and implies the nonexistence o
 f Serre invariant stability conditions when the degrees of the complete in
 tersection do not all coincide. This is joint work with Alexander Kuznetso
 v.\n
