Gorenstein toric Schubert varieties in Grassmannians
Gorenstein toric Schubert varieties in Grassmannians
A partial flag variety is a smooth projective homogeneous variety admitting an action of a maximal torus $T$. Schubert varieties are $T$-invariant subvarieties of the partial flag varieties. We study toric Schubert varieties in Grassmannian varieties with respect to the action of the torus $T$. Indeed, we present an explicit …
