Vector bundles [PDF]

open access: yes, 2008
This is the first volume of a three volume collection of Andrey Nikolaevich Tyurin's Selected Works. It includes his most interesting articles in the field of classical algebraic geometry, written during his whole career from the 1960s. Most of these papers treat different problems of the theory of vector bundles on curves and higher dimensional ...

Differential geometry of collective models

open access: yesAIMS Mathematics, 2019
The classical astrophysical theory of Riemann ellipsoids and the quantum nuclear theory of Bohr and Mottelson share a common mathematical foundation in terms of the differential geometry of a principal bundle ${\cal P}$ and its associated vector bundle E,

Stable rationality of higher dimensional conic bundles [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2018
We prove that a very general nonsingular conic bundle $X\rightarrow\mathbb{P}^{n-1}$ embedded in a projective vector bundle of rank $3$ over $\mathbb{P}^{n-1}$ is not stably rational if the anti-canonical divisor of $X$ is not ample and $n\geq 3$.

Trace formulae for curvature of Jet Bundles over planar domain

open access: yes, 2013
For a domain \Omega in \mathbb{C} and an operator T in \mathcal{B}_n(\Omega), Cowen and Douglas construct a Hermitian holomorphic vector bundle E_T over \Omega corresponding to T.

Prolongations of affine connection and horizontal vectors

open access: yesДифференциальная геометрия многообразий фигур, 2020
The linear frame bundle over a smooth manifold is considered. The mapping dе defined by the differentials of the first-order frame e is a lift to the normal N, i.

Semistability of Certain Bundles on Second Symmetric Power of a Curve

open access: yes, 2015
Let $C$ be a smooth irreducible projective curve and $E$ be a rank 2 stable vector bundle on $C$. Then one can associate a rank 4 vector bundle $\mathcal{F}_2(E)$ on $S^2(C)$, second symmetric power of $C$.

First and second cohomology group of a bu ndle

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
Let (E, π, M) be a vector bundle. We define two cohomology groups associated to π using the first and second order jet manifolds of this bundle. We prove that one of them is isomorphic with a Čech cohomology group of the base space.

Solutions of the Strominger System via Stable Bundles on Calabi-Yau Threefolds

open access: yes, 2012
We prove that a given Calabi-Yau threefold with a stable holomorphic vector bundle can be perturbed to a solution of the Strominger system provided that the second Chern class of the vector bundle is equal to the second Chern class of the tangent bundle.

Fibonacci, Golden Ratio, and Vector Bundles

open access: yesMathematics, 2021
There is a family of vector bundles over the moduli space of stable curves that, while first appearing in theoretical physics, has been an active topic of study for algebraic geometers since the 1990s. By computing the rank of the exceptional Lie algebra

Unfiltrable vector bundles and spanned vector bundles

open access: yesGulf Journal of Mathematics, 2016
Let X be an integral n-dimensional projective variety. We study the existence of rank r ≥ 2 vector bundles on X which are not extensions of two vector bundles (e.g. they exist if r=2 and X is a smooth surface with Kodaira dimension ≥ 0). Their existence implies the existence of many spanned rank n vector bundles E on X and (n+r)-dimensional linear ...
