Data base of around 50,000 planar dynamical systems.

Conference listings, survey articles, open problems, people, jobs, and seminars.

This set of lectures is designed to explore one-dimensional dynamical systems using the software Chaos and Dynamics.

A list of research sites maintained at the University of Warwick.

These notes study the dynamics of iterated holomorphic mappings from a Riemann surface to itself. The reader is assumed to be familiar with the rudiments of complex variable theory and of two-dimensional differential geometry.

Bulletin board and preprint archive.

This Java Applet can be used for the exploration on two-dimensional analytical defined dynamical systems. The system is defined by a set of two differential equations, which will be evaluated within adjustable regions forming a two-dimensional vector field.

A interactive laboratory on dynamical systems, in particular on particle systems.

Papers on population dynamics with hysteresis based on phase transition phenomena, by Emil Minchev (PDF/PS).

The Society seeks to promote the use of nonlinear methods in economics and finance from both a theoretical and empirical perspective.

References to several surveys and papers of introductory character which are available on-line.

Turbulent Landscapes is the result of 13 artists' explorations of complexity in nature. The exhibit will travel to museums and science centers in upcoming months.
