Radó theorem and its generalization for CR-mappings

Abstract

The following theorem is proved: Let M be a locally Lipschitz hypersurface in C^n with one-sided extension property at each point (e.g., without analytic discs). Let S be a closed subset of M and f : M \ S ---> C^m \ E is a CR-mapping of class L^{\infty} such that the cluster set of f on S along of Lebesque points of f is contained in a closed complete pluripolar set E. Then there is a CR-mapping f : M ---> C^m of class L^{\infty}(M) such that f |M§= f. It follows also that S is removable for CR \cap L^{\infty} (M \ S).
