Rudin's Theorem and Projective Hulls
Abstract
Walter Rudin, in 1966, characterized analytic functions in the unit disk in terms of the maximum principle relative to the boundary. We conjecture a generalization of this result when the disk is replaced by the punctured disk, and we prove a special case of this conjecture, making use of the notion of projective hull in Pn introduced by R. Harvey and B. Lawson.
