Jarnik and Julia; a Diophantine Analysis for Parabolic Rational Maps

In this paper we derive a Diophantine analysis for Julia sets of parabolic rational maps. We generalise two theorems of Dirichlet and Jarnik in number theory to the,theory of iterations of these maps. On the basis of these results, we then derive a 'weak multifractal analysis' of the conformal measure naturally associated with a parabolic rational map. The results in this paper contribute to a further development of Sullivan's famous dictionary translating between the theory of Kleinian groups and the theory of rational maps.
