	Vector - Wikipedia, the free encyclopedia
		Vector (spatial): In physics and engineering, vector most often refers specifically to an object that has a special relationship to the spatial coordinates/directions, that is, an element of a tangent bundle.
		A biological vector is a mechanism that transmits genes or organisms.
		Vector is the capital of the Empire in the videogame Final Fantasy VI.

	PlanetMath: vector bundle
		A vector bundle is a fiber bundle having a vector space as a fiber and the general linear group of that vector space (or some subgroup) as structure group.
		Sepcifically, if we want a topological vector bundle, we must supply a topological space for the base space, a topological space for the whole space, and the projection map must be continuous; this specifies a topology on each fiber.
		In the algebraic category, that is, vector bundles over schemes, there is a very nice correspondence between vector bundles and locally free sheaves; when the dimension is one and the scheme is nice enough, there is a further correspondence with Cartier divisors.

	Vector bundle (Site not responding. Last check: 2007-11-05)
		In mathematics, a vector bundle is a geometrical construct where to every point of a topological space (or manifold, or algebraic variety) we attach a vector space in a compatible way, so that all those vectorspaces, "glued together", form another topological space (or manifold or variety).
		A typical example is the tangent bundle of a differentiable manifold: to every point of the manifold we attach the tangent space of the manifold at that point.
		Smooth vector bundles are defined by requiring that E and X be smooth manifolds, π : E → X be a smooth map, and the local trivialization maps φ be diffeomorphisms.

	Cotangent bundle - Wikipedia, the free encyclopedia
		Because cotangent bundles can be thought of as symplectic manifolds, any real function on the cotangent bundle can be interpreted to be a Hamiltonian; thus the cotangent bundle can be understood to be a phase space on which Hamiltonian mechanics plays out.
		The one-form assigns to a vector in the tangent bundle of the cotangent bundle the application of the element in the cotangent bundle (a linear functional) to the projection of the vector into the tangent bundle (the differential of the projection of the cotangent bundle to the original manifold).
		The cylinder is the cotangent bundle of the circle.

	Tensor field - Encyclopedia, History and Biography
		There is the idea of vector bundle, which is a natural idea of 'vector space depending on parameters' — the parameters being in a manifold.
		The bundle of densities cannot seriously be defined 'at a point'; and therefore a limitation of the contemporary mathematical treatment of tensors is that tensor densities are defined in a roundabout fashion.
		The other vector bundles of tensors have comparable cocycles, which come from applying functorial properties of tensor constructions to the chain rule itself; this is why they also are intrinsic (read, 'natural') concepts.

	Fiber bundle
		In mathematics, in particular topology, a fiber bundle is a continuous surjective map, π from a topological space E to another topological space B, satisfying a further condition making it locally of a particularly simple form.
		For example in the case of a vector bundle, F is a vector space over the real numbers.
		An example of a principal bundle that occurs naturally in geometry is the bundle of all bases for the tangent space to a manifold, with G the general linear group ; restricting in Riemannian geometry to orthonormal bases, one would limit G to the orthogonal group.

		To see how the structure arises, first note that the vector bundle in R^n is R^2n, since there is a canonical isomorphism between all the tangent spaces.
		Also, a vector field on M is a differentiable mapping > v:M->TM which satisfies P(v(p)) = p, where P is the projection from TM onto > M. The tangent bundle on a smooth manifold is just one of many examples of vector bundles.
