Let be a fibered manifold over a manifold and be a homomorphism between Weil algebras and . Using the results of Mikulski and others, which classify product preserving bundle functors on the category of fibered manifolds, the author classifies all natural operators , where denotes the space of projective vector fields on and the bundle functors associated with .
