On the GIT quotient of Grassmannians by one dimensional torus

Narasimha Chary Bonala, S Senthamarai Kannan, Santosha Pattanayak

We consider the action of the one-parameter subgroup of the special linear group corresponding to a simple root on Grassmannians and describe the structure of the associated Geomet…

From Schubert Varieties to Doubly-Spherical Varieties

Mahir Bilen Can, S. Senthamarai Kannan, Pinakinath Saha

Horospherical Schubert varieties are determined. It is shown that the stabilizer of an arbitrary point in a Schubert variety is a strongly solvable algebraic group. The connectedne…

Torus quotients of Richardson varieties in $G_{r, q r + 1}$

S. Senthamarai Kannan, Arpita Nayek

Let $r$ and $q$ be positive integers and $n = q r + 1.$ Let $G = S L (n, C)$ and $T$ be a maximal torus of $G .$ Let $P^{α_{r}}$ be the maximal parabolic subgroup of $G$ correspondi…

On the geometry of the anti-canonical bundle of the Bott-Samelson-Demazure-Hansen varieties

Indranil Biswas, S. Senthamarai Kannan, Pinakinath Saha

Let $G$ be a semi-simple simply connected algebraic group over the field $C$ of complex numbers. Let $T$ be a maximal torus of $G,$ and let $W$ be the Weyl group of $G$ wi…

Minimal Parabolic subgroups and Automorphism groups of Schubert varieties-II

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 $G .$ In this ar…
