Abstract
Let be a conformal map of onto an unbounded domain and, for , let . If denotes the harmonic measure at of and denotes the hyperbolic distance between and in , then an application of the Beurling-Nevanlinna projection theorem implies that . Thus a natural question, first stated by P. Poggi-Corradini, is the following: Does there exist a positive constant such that for every , ? In general, we prove that the answer is negative by means of two different examples. However, under additional assumptions involving the number of components of and the hyperbolic geometry of the domain , we prove that the answer is positive.
