Counting Hyperbolic Components
We give formulas for the numbers of type II and type IV hyperbolic components
in the space of quadratic rational maps, for all fixed periods of attractive
cycles
Hyperbolic Components in Exponential Parameter Space
We discuss the space of complex exponential maps \Ek\colon z\mapsto
e^{z}+\kappa. We prove that every hyperbolic component has connected
boundary, and there is a conformal isomorphism \Phi_W\colon W\to\half^- which
extends to a homeomorphism of pairs \Phi_W\colon(\ovl
W,W)\to(\ovl\half^-,\half^-). This solves a conjecture of Baker and Rippon,
and of Eremenko and Lyubich, in the affirmative. We also prove a second
conjecture of Eremenko and Lyubich.Comment: To appear in: Comptes Rendues Acad Sci Paris.-- Detailed description
