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 
, corresponding to omitting α
0; α
d
) which is a natural compactification of the cotangent bundle to the Grassmann variety.
