Vector bundles on G(1,4) without intermediate cohomology [PDF]

open access: yesarXiv, 1998
We characterize the vector bundles on G(1,4) that have no intermediate cohomology. We obtain them from extensions of the universal bundles and others related with them.

On the Buchsbaum index of rank two vector bundles on P3 [PDF]

open access: yesarXiv, 2015
We classify rank two vector bundles on P3 with Buchsbaum index equal to three and also give some results on the H1-module of "negative instanton"bundles.Comment: Submitted to the proceedings of the Pau-Trieste conferences Vector bundles ...

Regulous vector bundles [PDF]

open access: yesarXiv, 2017
Among recently introduced new notions in real algebraic geometry is that of regulous functions. Such functions form a foundation for the development of regulous geometry.

Cohomological characterization of vector bundles on multiprojective spaces [PDF]

open access: yes, 2005
We show that Horrock's criterion for the splitting of vector bundles on $\PP^n$ can be extended to vector bundles on multiprojective spaces and to smooth projective varieties with the weak CM property (see Definition 3.11).

Strictly nef vector bundles and characterizations of ℙn

open access: yesComplex Manifolds, 2021
In this note, we give a brief exposition on the differences and similarities between strictly nef and ample vector bundles, with particular focus on the circle of problems surrounding the geometry of projective manifolds with strictly nef bundles.

New Properties of Multiplier Submodule Sheaves

open access: yesComptes Rendus. Mathématique, 2022
In this note, we establish the strong openness and stability property of multiplier submodule sheaves associated to singular Nakano semi-positive metrics on holomorphic vector bundles, which generalizes the same properties for multiplier ideal sheaves ...

OBSTRUCTIONS TO ALGEBRAIZING TOPOLOGICAL VECTOR BUNDLES

open access: yesForum of Mathematics, Sigma, 2019
Suppose $X$ is a smooth complex algebraic variety. A necessary condition for a complex topological vector bundle on $X$ (viewed as a complex manifold) to be algebraic is that all Chern classes must be algebraic cohomology classes, that is, lie in the ...

Chern classes of automorphic vector bundles, II [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2019
We prove that the $\ell$-adic Chern classes of canonical extensions of automorphic vector bundles, over toroidal compactifications of Shimura varieties of Hodge type over $\bar{ \mathbb{Q}}_p$, descend to classes in the $\ell$-adic cohomology of the ...

Vector bundles over three-dimensional spherical space forms

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
We consider the problem of enumerating the G-bundles over low-dimensional manifolds (dimension ≤3) and in particular vector bundles over the three-dimensional spherical space forms.

Simple vector bundles on plane degenerations of an elliptic curve [PDF]

open access: yes, 2009
In 1957 Atiyah classified simple and indecomposable vector bundles on an elliptic curve. In this article we generalize his classification by describing the simple vector bundles on all reduced plane cubic curves.
