Overview

Via this web page you will create a PDF book on rational mathematical modelling of dynamics tailored to the interests you specify. Currently this is an early draft version, an alpha version.

Among the sections that follow, choose the interesting ones

At the end click Submit to process and produce a PDF book tailored just for you---the processing automatically detects all the prerequisite sections and includes them as well---only click what interests you.

But first, what computer algebra package do you prefer?
Reduce (recommended)
Maple (as yet only available in Chapter 1)
Mathematica (as yet only available in Chapter 1, thanks to Rick Eller)

Asymptotic methods solve algebraic and differential equations
Perturbed algebraic equations solved iteratively
Power series solve ordinary differential equations
The normal form of oscillations give their amplitude and frequency

Nonlinear evolution of double diffusion
N/A Chaos appears in triple convection

Avoid memory in modelling stochastic systems

Large-scale spatial variations
Poiseuille pipe flow
Dispersion in pipes

Slow manifolds guide the mean dynamics
Incompressible and other approximations
Sub-centre and slow manifolds
N/A Water waves

Patterns form and evolve
One-dimensional introduction
N/A Two-dimensional spatio-temporal patterns
N/A Embedding slow dynamics
for processing.
Wait for perhaps up to a minute or so for the results page to load---the results page will load only after the book has been typeset (or failed as the case may be).

Print the book 2up

The book is typeset onto A5 paper (in colour) so please save forests and print 2 pages per sheet of paper. Also, A5 is by far the best standard size for reading electronically on your computer screen.
