Schur rigidity of Schubert varieties in rational homogeneous manifolds of Picard number one

Jaehyun Hong, Ngaiming Mok

Given a rational homogeneous manifold $S=G/P$ of Picard number one and a Schubert variety $S_0$ of $S$, the pair $(S,S_0)$ is said to be homologically rigid if any subvariety of $…
