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…

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…

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…
