Algebraic loop groups and moduli spaces of bundles
Gerd FaltingsMax-Planck-Institut für Mathematik, Bonn, Germany
We study algebraic loop groups and affine Grassmannians in positive characteristic. The main results are normality of Schubert-varieties, the construction of line-bundles on the affine Grassmannian, and the proof that they induce line-bundles on the moduli-stack of torsors.
