Infinite-dimensional Thurston theory and transcendental dynamics III: entire functions with escaping singular orbits in the degenerate case
arXiv:2104.12206 · doi:10.3934/dcds.2026118
Abstract
We classify transcendental entire functions that are compositions of a polynomial and the exponential for which all singular values escape on disjoint rays. We focus on the case where the escape is degenerate in the sense that points from different singular orbits are arbitrarily close to each other. As in the general case we employ an iteration procedure on an infinite-dimensional Teichmüller space, analogously to the Thurston's classical Topological Characterization of Rational Functions, but for an infinite set of marked points.
