rectification theorem
Let U be an open subset of ℝn and let f∈C1(U) be a continuous differentiable
vector field
f:U→ℝn. |
If there exists x0∈U such that f(x0)≠0 then there exists U0⊂U an open neighborhood of x0 such that there exists a diffeomorphism of class C1
F:U0→V |
where V is an open subset of ℝn such that
[DF(x)]f(x)=e1 |
for all x∈U0 where [DF(x)] is the Jacobian of the diffeomorphism F evaluated at x and e1=(1,0,…,0) is the first vector of the canonical basis of ℝn. More generally if the vector field f is of class Cr then so is the diffeomorphism F. [AVI]
