On homogeneous vector bundles

open access: yesBulletin des Sciences Mathématiques, 2008
AbstractLet G be a simply connected linear algebraic group, defined over the field of complex numbers, whose Lie algebra is simple. Let P be a proper parabolic subgroup of G. Let E be a holomorphic vector bundle over G/P such that E admits a homogeneous structure. Assume that E is not stable.

Weakly uniform rank two vector bundles on multiprojective spaces [PDF]

open access: yes, 2010
Here we classify the weakly uniform rank two vector bundles on multiprojective spaces. Moreover we show that every rank $r>2$ weakly uniform vector bundle with splitting type $a_{1,1}=...=a_{r,s}=0$ is trivial and every rank $r>2$ uniform vector bundle ...

Totally Geodesic Submanifolds in Tangent Bundle with g - natural Metric [PDF]

open access: yes, 2013
In the paper we investigate submanifolds in a tangent bundle endowed with g-natural metric G, defined by a vector field on a base manifold. We give a sufficient condition for a vector field on M to defined totally geodesic submanifold in (TM,G).

Weighted E-Spaces and Epistemic Information Operators

open access: yesInformation, 2014
Information is usually related to knowledge. Here, we present a broader picture in which information is associated with epistemic structures, which form cognitive infological systems as basic recipients and creators of cognitive information.

Lifting vector bundles to Witt vector bundles

open access: yes, 2018
Let $X$ be a scheme. Let $r \geq 2$ be an integer. Denote by $W_r(X)$ the scheme of Witt vectors of length $r$, built out of $X$. We are concerned with the question of extending (=lifting) vector bundles on $X$, to vector bundles on $W_r(X)$-promoting a systematic use of Witt modules and Witt vector bundles. To begin with, we investigate two elementary

Super Vector Bundles

open access: yesJournal of Physics: Conference Series, 2011
We review the basic aspects of the theory of smooth super vector bundles. In particular we give the precise link existing between the geometrical and the sheaf theoretical approaches.

Vector bundles and blowups [PDF]

open access: yes, 2017
Let X be a nonsingular quasi-projective complex algebraic variety and let E be an algebraic vector bundle on X of rank r ≥ 2. The pullback of E by the blowup of X at a suitably chosen nonsingular subvariety of X of codimension r contains a line subbundle that can be explicitly described.

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.

On automorphisms of vector bundles

open access: yesJournal of Pure and Applied Algebra, 1974
AbstractA finite group G is isomorphic to a group of automorphisms of a real indecomposable vector bundle ψ over a paracompact space B if and only if G is isomorphic to a subgroup of the multiplicative group of the division algebra of real quaternions.
