Singular orbits and Baker domains
arXiv:2009.07020 · doi:10.1007/s00208-020-02132-z
Abstract
We show that there is a transcendental meromorphic function with an invariant Baker domain such that every singular value of is a super-attracting periodic point. This answers a question of Bergweiler from 1993. We also show that can be chosen to contain arbitrarily large round annuli, centred at zero, of definite modulus. This answers a question of Mihaljević and the author from 2013, and complements recent work of Barański et al concerning this question.
