Schur flexibility of cominuscule Schubert varieties

Journal Article (Journal Article)

Let X = G/P be a cominuscule rational homogeneous variety. (Equivalently, X admits the structure of a compact Hermitian symmetric space.) We say a Schubert class ξ is Schur rigid if the only irreducible subvarieties Y X with homology class [Y] ε Zξ are Schubert varieties. Robles and The identified a sufficient condition for ξ to be Schur rigid. In this paper, we show that the condition is also necessary.
