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…

Some combinatorial aspects of generalised Bott-Samelson varieties

Michel Brion, S. Senthamarai Kannan

We obtain two combinatorial results: an equality of Weyl groups and an inequality of roots, in the setting of generalised Bott-Samelson resolutions of minuscule Schubert varieties.…

Minimal rational curves on generalized Bott-Samelson varieties

Michel Brion, S. Senthamarai Kannan

We investigate families of minimal rational curves on Schubert varieties, their Bott-Samelson desingularizations, and their generalizations constructed by Nicolas Perrin in the min…

Rigidity of Bott-Samelson-Demazure-Hansen variety for $P S O (2 n + 1, C)$

S. Senthamarai Kannan, Pinakinath Saha

Let $G = P S O (2 n + 1, C) (n \geq 3)$ and $B$ be the Borel subgroup of $G$ containing maximal torus $T$ of $G .$ Let $w$ be an element of Weyl group $W$ and $X (w)$ be the Schubert…

Rigidity of Bott-Samelson-Demazure-Hansen variety for $F_{4}$ and $G_{2}$

S. Senthamarai Kannan, Pinakinath Saha

Let $G$ be a simple algebraic group of adjoint type over $C,$ whose root system is of type $F_{4} .$ Let $T$ be a maximal torus of $G$ and $B$ be a Borel subgroup of $G$ co…

Parabolic subgroups and Automorphism groups of Schubert varieties

S. Senthamarai Kannan, Pinakinath Saha

Let $G$ be a simple algebraic group of adjoint type over the field $C$ of complex numbers, $B$ be a Borel subgroup of $G$ containing a maximal torus $T$ of $G .$ Let $w$ be…
