A note on the Gromov width of toric manifolds
Narasimha Chary Bonala, Stéphanie Cupit-Foutou
The Gromov width of a uniruled projective Kähler manifold can be bounded from above by the symplectic area of its minimal curves. We apply this result to toric varieties and thus g…
A note on toric degeneration of a Bott-Samelson-Demazure-Hansen variety
B. Narasimha Chary
In this paper we study the geometry of toric degeneration of a Bott-Samelson-Demazure-Hansen (BSDH) variety. We give some applications to BSDH varieties. Precisely, we classify Fan…
On Mori cone of Bott towers
B. Narasimha Chary
A Bott tower of height is a sequence of projective bundles $$X_r \overset{π_r}\longrightarrow X_{r-1} \overset{π_{r-1}}\longrightarrow \cdots \overset{π_2}\longrightarrow X_1=\…
