In this work, we study a family of first-order partial differential operators defined in a neighborhood of an invariant torus Tm0 : = Tm x ⊂ Tm x Rn. These operators have orbits (in the sense of Sussmann) which are contained in Tm0. We prove that, if a certain diophantine condition (of Siegel-type) is satisfied, it is possible to determine a normal form for these operators in a neighborhood of the invariant torus. In this case, we also prove a semiglobal solvability result. We discuss the problem in the C∞ (smooth) and Cω (real-analytic) categories. (AU)
