On a Lie's theorem about integrability by quadratures
We present a substantial generalisation of a classical result by Lie on integrability by quadratures.
Namely, we prove that all vector fields in a finite-dimensional
transitive and solvable Lie algebra of vector fields on a manifold can be integrated by quadratures.
