Smooth vector bundles

This file defines smooth vector bundles over a smooth manifold.

Let E be a topological vector bundle, with model fiber F and base space B. We consider E as carrying a charted space structure given by its trivializations -- these are charts to B × F. Then, by "composition", if B is itself a charted space over H (e.g. a smooth manifold), then E is also a charted space over H × F.

Now, we define SmoothVectorBundle as the Prop of having smooth transition functions. Recall the structure groupoid smoothFiberwiseLinear on B × F consisting of smooth, fiberwise linear partial homeomorphisms. We show that our definition of "smooth vector bundle" implies HasGroupoid for this groupoid, and show (by a "composition" of HasGroupoid instances) that this means that a smooth vector bundle is a smooth manifold.

Since SmoothVectorBundle is a mixin, it should be easy to make variants and for many such variants to coexist -- vector bundles can be smooth vector bundles over several different base fields, they can also be C^k vector bundles, etc.

Main definitions and constructions

• FiberBundle.chartedSpace: A fiber bundle E over a base B with model fiber F is naturally a charted space modelled on B × F.

• FiberBundle.chartedSpace': Let B be a charted space modelled on HB. Then a fiber bundle E over a base B with model fiber F is naturally a charted space modelled on HB.prod F.

• SmoothVectorBundle: Mixin class stating that a (topological) VectorBundle is smooth, in the sense of having smooth transition functions.

• SmoothFiberwiseLinear.hasGroupoid: For a smooth vector bundle E over B with fiber modelled on F, the change-of-co-ordinates between two trivializations e, e' for E, considered as charts to B × F, is smooth and fiberwise linear, in the sense of belonging to the structure groupoid smoothFiberwiseLinear.

• Bundle.TotalSpace.smoothManifoldWithCorners: A smooth vector bundle is naturally a smooth manifold.

• VectorBundleCore.smoothVectorBundle: If a (topological) VectorBundleCore is smooth, in the sense of having smooth transition functions (cf. VectorBundleCore.IsSmooth), then the vector bundle constructed from it is a smooth vector bundle.

• VectorPrebundle.smoothVectorBundle: If a VectorPrebundle is smooth, in the sense of having smooth transition functions (cf. VectorPrebundle.IsSmooth), then the vector bundle constructed from it is a smooth vector bundle.

• Bundle.Prod.smoothVectorBundle: The direct sum of two smooth vector bundles is a smooth vector bundle.

Smoothness of maps in/out fiber bundles

Note: For these results we don't need that the bundle is a smooth vector bundle, or even a vector bundle at all, just that it is a fiber bundle over a charted base space.
