Let be the Heisenberg group of dimension . Let be the partial sub-Laplacians on and the central element of the Lie algebra of . We prove that the kernel of the operator is in the Schwartz space if . We prove also that the kernel of the operator is in if and that the kernel of the operator is in if . Here is the Kohn-Laplacian on .
