DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GRT-2020/17/
 ">Global Demazure modules</a>\nby Michael Finkelberg (HSE Moscow) as part 
 of Geometric Representation Theory conference\n\n\nAbstract\nThe Beilinson
 -Drinfeld Grassmannian of a simple complex algebraic group admits a natura
 l stratification into "global spherical Schubert varieties". In the case w
 hen the underlying curve is the affine line\, we determine algebraically t
 he global sections of the determinant line bundle over these global Schube
 rt varieties as modules over the corresponding Lie algebra of currents. Th
 e resulting modules are the global Weyl modules (in the simply laced case)
  and generalizations thereof. This is a joint work with Ilya Dumanski and 
 Evgeny Feigin.\n
