For a vector field X on a manifold M we have, at least locally and for short time, a flow ψ t of X. If X is regular at some point, we can find coordinates rectifying the vector field such that ∂ 1 = X. Then the representation of ψ t is just ( x 1 + t, …, x n). But the representation of the differential d ψ t: T p M → T ψ t ( p) M ...
