A classification of spherical Schubert varieties in the Grassmannian

Reuven Hodges, Venkatramani Lakshmibai

Let $L$ be a Levi subgroup of $G L_{N}$ which acts by left multiplication on a Schubert variety $X (w)$ in the Grassmannian $G_{d, N}$ . We say that $X (w)$ is a spherical Schubert variet…

Toroidal Schubert Varieties

Mahir Bilen Can, Reuven Hodges, Venkatramani Lakshmibai

Levi subgroup actions on Schubert varieties are studied. In the case of partial flag varieties, the horospherical actions are determined. This leads to a characterization of the to…

Sphericality and Smoothness of Schubert Varieties

Mahir Bilen Can, Reuven Hodges

We consider the action of the Levi subgroup of a parabolic subgroup that stabilizes a Schubert variety. We show that a smooth Schubert variety is a homogeneous space for a paraboli…
