The exponential map is chaotic: An invitation to transcendental dynamics

Dynamical Systems 2020-08-26 v2 Complex Variables

Abstract

We present an elementary and conceptual proof that the complex exponential map is "chaotic" when considered as a dynamical system on the complex plane. (This result was conjectured by Fatou in 1926 and first proved by Misiurewicz 55 years later.) The only background required is a first undergraduate course in complex analysis.
