The process of finding f¢ for an entire function f has infinite topological entropy

Héctor Méndez-Lango

Let (H(C), r) be the metric space of all entire functions f where the metric r induces the topology of uniform convergence on compact subsets of the complex plane. Let D: H(C) ® H(C) be the linear mapping that assigns to each f its derivative, D(f) = f¢. We show in this note that there exists a compact subset of H(C), say K, that is invariant under D, and D restricted to K has infinite topological entropy.

Keywords: Topological entropy, chaotic maps
