Abstract

The purpose of this paper is to establish local regularity of the solution operator to the Kohn-Laplace equation, called the complex Green operator, on abstract CR manifolds of hypersurface type. For a cut-off function σ, we introduce the σ-superlogarithmic property, a potential theoretical condition on CR manifolds. We prove that if the given datum is smooth on an open set containing the support of σ then the solution is smooth on the interior of \x∈ M:σ(x)=1\. Furthermore, we also study the smoothness of the integral kernel of the complex Green operator.
