DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VCAS/112/">C
 ohomology of line bundles on the incidence correspondence</a>\nby Claudiu 
 Raicu (University of Notre Dame) as part of IIT Bombay Virtual Commutative
  Algebra Seminar\n\n\nAbstract\nLet X denote the incidence correspondence 
 (or partial flag variety) parametrizing pairs consisting of a point in pro
 jective space and a hyperplane containing it. I will explain how to charac
 terize the vanishing and non-vanishing behavior of the cohomology groups o
 f line bundles on X over an arbitrary field. For the projective plane\, th
 e results are contained in the thesis of Griffith from the 70s\, while in 
 characteristic zero the cohomology groups are described in any dimension b
 y the Borel-Weil-Bott theorem. Joint work with Zhao Gao.\nChairperson - Be
 rnd Ulrich\n
