A portion of this work represents part of the author's doctoral dissertation written at the University of Michigan. I would like to thank Professor Wolfgang H. Fuchs of Cornell University, who pointed out that Theorem 2 could be deduced directly from Theorem 1; Charles A. Micchelli, of I.B.M. Research, for discussion of the ideas in the proof of Lemma 4 and for bringing Fenchel's theorem to my attention; and my thesis advisor, Professor Peter L. Duren, for his assistance in this project.
