Abstract

We shall show that Beurling-Tsuji’s theorem (see Theorem A) is, in a sense, best possible. For each pair a , b ( 0 , + ) a, b \in (0, + \infty ) there exists a function f holomorphic in { | z | > 1 } \{ |z| > 1\} such that the Euclidean area of the Riemannian image of each non-Euclidean disk of non-Euclidean radius a, is bounded by b, and such that f has finite angular limit nowhere on the unit circle.
