Mumford's stability on the Sato Grassmannian

Description:  We give a notion of stability on the infinite Grassmannian Gr(k((z))^{\oplus r}) for the action of the group Sl(r,k[[z]]) coherent with the classic stability notion for vector bundles over a curve. We give a numerical criterium and prove the existence of some geometric quotients. Area(s): Date:  2007-06-26 Start Time:   14:45 Speaker:  Ana Casimiro (Mat.
