Abstract

A generalization of a result of Wermer concerning the existence of polynomial hulls without analytic discs is presented. As a consequence it is shown that there exists a Cantor set XX in C3{\mathbb C}^3 whose polynomial hull is strictly larger than XX but contains no analytic discs.

The paper has been almost completely rewritten. A much shorter, but less direct, proof is given that yields a stronger result
