Let G be a simply connected semisimple algebraic group and B be a Borel subgroup. Schubert varieties in the flag variety G/B are closely connected to Demazure modules via a Borel-Weil theorem. This relationship has analogues for affine Schubert varieties and affine Demazure modules. In this talk, I will further present a Borel-Weil type theorem for the Beilinson-Drinfeld Schubert varieties associated with parahoric group schemes and twisted global Demazure modules. This is joint work with Jiuzu Hong.
