We discuss the wellposedness of the Neumann problem on a half-space for the Kohn-Laplacian in the Heisenberg group. We then construct the Neumann function and explicitly represent the solution of the associated inhomogeneous problem.

Keywords: Neumann problem, Heisenberg group, sub-Laplacian, horizontal normal vectors, Neumann function
