J.D. Murray, Springer, 2004
Anything on Phil Maini's publ list !
Prerequisites
Mathematics
Some differential equations
Some basic linear algebra (eigenvalues, etc)
Some Fourier series
Computing. You will be required to do some computer exercises. Free software
XPPAUT
is available that will allow you to do most of the exercises. However, if you are more comfortable with MatLab, or other software, by all means use it.
