Smooth torus quotients of Schubert varieties in the Grassmannian

Sarjick Bakshi, S. Senthamarai Kannan, K. Venkata Subrahmanyam

Let $r<n$ be positive integers and further suppose $r$ and $n$ are coprime. We study the GIT quotient of Schubert varieties $X(w)$ in the Grassmannian $G_{r,n}$, admitting semist…
