Degenerate Flag Varieties of Type A and C are Schubert Varieties
Copyright policy )Degenerate Flag Varieties of Type A and C are Schubert Varieties
We show that in type A or C any degenerate flag variety is in fact isomorphic to a Schubert variety in an appropriate partial flag manifold.
The new version includes an appendix where we discuss desingularizations. 14 pages
