We consider planar vector fields without zeroes ΞΎ and study the image of the associated Lie derivative operators L ΞΎ acting on the space of smooth functions. We show that the cokernel of L ΞΎ is infinite-dimensional as soon as ΞΎ is not topologically conjugate to a constant vector field and that, if t
