Hyperbolic components in exponential parameter space
[Composantes hyperboliques dans l'espace des applications exponentielles.]
Comptes Rendus. Mathématique, Volume 339 (2004) no. 3, pp. 223-228.

Nous étudions l'espace des applications exponentielles complexes Eκ:zez+κ. Nous démontrons que pour chaque composante hyperbolique W, le bord ∂W est connexe, et qu'il y a un isomorphisme biholomorphe ΦW:WH qui s'étend en un homéomorphisme de paires ΦW:(W¯,W)(H¯,H). Ceci établit une conjecture de Baker et Rippon, et de Eremenko et Lyubich. D'autre part, nous démontrons une autre conjecture de Eremenko et Lyubich.

We discuss the space of complex exponential maps Eκ:zez+κ. We prove that every hyperbolic component W has connected boundary, and there is a conformal isomorphism ΦW:WH which extends to a homeomorphism of pairs ΦW:(W¯,W)(H¯,H). 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.
