C^n
sections #
In this file we define the type ContMDiffSection
of n
times continuously differentiable
sections of a vector bundle over a manifold M
and prove that it's a module over the base field.
In passing, we prove that binary and finite sums, differences and scalar products of C^n
sections are C^n
.
The scalar product ψ • s
of a C^k
function ψ : M → 𝕜
and a section s
of a vector
bundle V → M
is C^k
once s
is C^k
on an open set containing tsupport ψ
.
This is a vector bundle analogue of contMDiff_of_tsupport
.
The sum of a locally finite collection of sections is C^k
iff each section is.

The sum of a locally finite collection of sections is C^k
at x
