Heriot-Watt University - Masterclass material

For several years the Universities of Heriot-Watt and Edinburgh have been running Masterclasses for the brightest mathematics school students in Lothian Region. The pupils, aged about 13, spend 2 1/2 hrs each Saturday studying recent developments in Mathematics such as chaos, fractals, evolutionary games, etc. Some of these classes involve using purpose-built interactive computer programs to illustrate, for example, the construction of a fractal curve. We are now beginning to put this material up on WWW to make it available to a wider audience. Visit our site at to see what is available, or email Chris Eilbeck

New Bifurcation software: CONTENT 1.3

This is to inform that new CONTENT 1.3 is now available by ftp. CONTENT is a multi-platform interactive environment to study dynamical systems. It is designed to perform simulation, continuation, and normal form analysis of dynamical systems appearing in research and engineering.

1. This version of CONTENT supports:

For ODEs:

For iterated maps: For PDEs on the unit interval: 2. CONTENT provides: 3. How to get CONTENT

CONTENT 1.3 is freely available by anonymous ftp from (

cd pub
get source_file target_file
Here source_file is one of the following:

These files contain binary executables for running on the corresponding platform (hardware+OS[+complier]), as well as example dynamical systems.

The target_file is:

content.tar.gz for Unix (SGI, Sun, DEC, HP, PC Linux) for MS Windows
Please, follow instructions in the README file to install CONTENT on your system.

4. Software requirements for CONTENT

Unix: C and C++ compilers must be accessible via the PATH variable, as well as the X11, X toolkit and Motif libraries via the LD_LIBRARY_PATH variable.

MS_Windows: Borland C++ compiler 5.0 must be installed. CONTENT uses only command line compiler bcc32.

We wish you success in using CONTENT!

Complexity and management mail list

A shared language based on the new science of complexity can have an important role in managerial sense making. The use of complexity theory can change the way managers think about the problems they face. Instead of competing in a game or a war, managers of a complexity thinking enterprise are trying to find their way on an ever changing, ever turbulent landscape. Such a conception of their organisations' basic task can, in turn, change the day-to-day decisions made by management. The most productive applications of complexity language have to do with new possibilities for innovation. These possibilities require new ways of thinking, but old models of thinking persist long after they are productive. New ways of thinking don't just happen; they require both discussion and support.

Our complexity and management mail list carries messages directed to:

Our 500 members range from academics to managers. The list is totally free. Note this is a busy discussion forum with more than 10 messages each day.

CALResCo web site

The Complexity & Artificial Life Research Concept
for Self-Organising Systems

The CALResCo web site is devoted to complexity and non-linear issues. We try to provide information for newcomers via introductions and links to tutorials, plus access to relevant technical papers, applications and online sites.

Orthogonal Polynomials, Integral Transforms and Solutions for Dynamics of Multilevel Systems

A group at International Sakharov Institute of Radioecology are studying multiphoton excitation of molecules by infrared laser radiation. We try to find analytic solutions of the dynamic equations using miscellaneous orthogonal polynomials (Gegenbauer, Jacobi, Pollaczek, Laguerre, Meixner, Krawtchouk, Hahn etc.).

For information have a look at:

From Calculus to Chaos

The new book From Calculus to Chaos has just been published by Oxford University Press (paperback price 14.95 pounds).

As the title implies, it has quite a wide range, and is intended for a very wide readership, but it does contain some introductory material on nonlinear systems, together with some novice-friendly computer programs. These "Ten programs for exploring dynamics" can be downloaded, if desired, from my web site where further details of the book may be found.

Dynamics Days 1998

The UK will be hosting Dynamics Days 1998. Supported by the LMS, the meeting will be held during the period 28 June - 1 July 1998, hosted in Edinburgh by the ICMS. A full programme of speakers will be announced in due course and full details of registration etc will follow to individual departments. In the meantime, any informal queries should be addressed to John Hogan ( or John Brindley
