Cotangent bundle to the Grassmann variety

Published 30 Apr 2015 in math.AG | (1505.00038v1)

Abstract: We show that there is an affine Schubert variety in the infinite dimensional partial Flag variety (associated to the two- step parabolic subgroup of the Kac-Moody group {\hat SL(n)}, corresponding to omitting {\alpha}_0,{\alpha}_d) which is a natural compactification of the cotangent bundle to the Grassmann variety.
