Algebra and Geometry of Irreducible toric vector bundles of rank $n$ on $\mathbb{P}^n$ (2308.09017v1)

Abstract: We construct a presentation for the Cox ring of the projectivization $\mathbb{P}\mathcal{E}$ of any rank $n$ irreducible toric vector bundle on $\mathbb{P}^n$. We use this presentation to show that $\mathbb{P}\mathcal{E}$ always satisfies Fujita's freeness and ampleness conjectures.
