Dynamics in One Complex Variable

Yakov Shapiro has written a java applet that illustrates the results in our paper on singularly perturbed quadratic maps. The applet can be found here.

The following is a program that Yakov Shapiro has developed while working with me in the summer of 2001. We were interested in studying the bifurcations of the reversible, area preserving complex Henon Map. The program is in principle able to parse all quadratic polynomial maps in C^2. You can download the .txt files for information on how to install and use the program.

The program StCurve.exe will draw the intersection of the stable manifold of the saddle point of the Henon Map with a plane that can be specified by the user.

This program will unfortunately only run on a PC.
