A CHARACTERIZATION OF AUTOMORPHISMS OF THE UNIT DISC BY THE POINCARE ́ METRIC

초록

Non-trivial automorphisms of the unit disc in the complex plane can be classified by three classes; elliptic, parabolic and hyperbolic automorphisms. This classification is due to a representation in the pro- jective special linear group of the real field, or in terms of fixed points on the closure of the unit disc. In this paper, we will characterize this classi- fication by the distance function of the Poincar ́e metric on the interior of the unit disc.
