LetRbe a principal ideal domain containing ℚ and let ξ be a nonzero locally nilpotent derivation of the polynomial ringA=R[2]. We prove in this paper thatAis a free module over the kernel of ξ and has a ξ-basis. As a consequence, given a fieldKof characteristic zero, we obtain that the freeness Conjecture of Freudenburg [12] holds for locally nilpotent derivations ofK[3]having rank at most two.
