Equivariant $K$ -theory of quasitoric manifolds

Jyoti Dasgupta, Bivas Khan, V. Uma

Let $X (Q, Λ)$ be a quasitoric manifold associated to a simple convex polytope $Q$ and characteristic function $Λ$ . Let $T ≅ (S^{1})^{n}$ denote the compact $n$ -torus acting…

Cohomology of torus manifold bundles

Jyoti Dasgupta, Bivas Khan, V. Uma

Let $X$ be a torus manifold with locally standard action of a compact torus $T$ 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…
