This requires a careful analysis due also to the non-homogeneous nature of the full Laplacian. This result has to be compared to a previous one by Bahouri, Gérard and Xu concerning the solution of the wave equation related to the Kohn-Laplacian.22 pages, 1 figureAnalysis of PDEsClassical Analysis and ODEs22E25, 35B65text
