Query: Degenerate Schubert Varieties in Type A   We introduce rectangular elements in the symmetric group. In the framework of
PBW degenerations, we show that in type A the degenerate Schubert variety
associated to a rectangular element is indeed a Schubert variety in a partial
flag variety of the same type with larger rank. Moreover, the degenerate
Demazure module associated to a rectangular element is isomorphic to the
Demazure module for this particular Schubert variety of larger rank. This
generalizes previous results by Cerulli Irelli, Lanini and Littelmann for the
PBW degenerate flag variety.
