Topology, Combinatorics, and Dynamics of Rational Maps

In this talk, we discuss the following question first popularized in the 1980s by the then startling new computer renderings of the Mandelbrot set. Given a rational map from the Riemann sphere to itself, how does the behavior of the map near the forward orbits of the critical points determine the rational map itself? This circle of ideas, developed by Douady-Hubbard, Thurston, Milnor and others draws from classical ideas in complex analysis, topology and algebraic geometry. We will give a brief survey, and state some recent results and open questions
