Analytic mappings of the unit disk which almost preserve hyperbolic area

Complex Variables 2024-09-24 v2 Classical Analysis and ODEs

Abstract

In this paper, we study analytic self-maps of the unit disk which distort hyperbolic area of large hyperbolic disks by a bounded amount. We give a number of characterizations involving angular derivatives, Lipschitz extensions, M\"obius distortion, the distribution of critical points and Aleksandrov-Clark measures. We also study Lyapunov exponents of their Aleksandrov-Clark measures.
