Anthony G. O'Farrell: MT522 Complex Dynamical Systems



For postgraduates.

Content:

Dynamics of polynomial and rational maps in one complex variable.

We assume a knowledge of elementary complex analysis, and some competence with a symbolic manipulator and a programming language. I'll begin by explaining further background material in complex analysis, including material about univalent functions, uniformization, and the Riemann-Hurwicz formula. I'll also cover the basics of quasiconformal mappings and singular integral operators.

The course will approximate to the first half or so of Carleson & Gamelin's book on Complex Dynamics, which I recommend you buy. We will go as far as Sullivan's theorem on non-wandering domains.

You will have the opportunity to do some practical work, using Maple ond/or a language of your choice. There will also be theoretical homework to do.
