Geometric mitosis

We describe an elementary convex geometric algorithm for realizing Schubert cycles in complete flag varieties by unions of faces of polytopes. For GL n and Gelfand–Zetlin polytopes, combinatorics of this algorithm coincides with that of the mitosis on ...

. Consider the natural action of GL n ( C ) on p covectors and q vectors; by Howe duality, the space of polynomial functions on this space decomposes multiplicity-free under the joint action of GL n ( C ) and gl p + q ( C ) . When n (cid:21) p + q (which
