Seshadri constants of equivariant vector bundles on toric varieties
Jyoti Dasgupta, Bivas Khan, Aditya Subramaniam
We compute Seshadri constants of a torus equivariant nef vector bundle on a projective space satisfying certain conditions. As an application, we compute Seshadri constants of tang…
Stability of equivariant vector bundles over toric varieties
Jyoti Dasgupta, Arijit Dey, Bivas Khan
We give a complete answer to the question of (semi)stability of tangent bundle of any nonsingular projective complex toric variety with Picard number 2 by using combinatorial criet…
Equivariant -theory of quasitoric manifolds
Jyoti Dasgupta, Bivas Khan, V. Uma
Let be a quasitoric manifold associated to a simple convex polytope and characteristic function . Let denote the compact -torus acting…
Cohomology of torus manifold bundles
Jyoti Dasgupta, Bivas Khan, V. Uma
Let be a torus manifold with locally standard action of a compact torus of half the dimension and orbit space a homology polytope. Smooth complete complex toric varieties a…
Toric vector bundles on Bott tower
Bivas Khan, Jyoti Dasgupta
In this paper, using Klyachko's classification theorem we study positivity and semi-stability of toric vector bundles on a class of nonsingular projective toric varieties, known as…
