Some useful Mathematica add-on packages

• BifCurve is a package for continuation of bifurcations of equilibria using a locally-parameterized adaptive step, prediction-correction algorithm
• NormalForm computes Poincare normal forms of vectorfields. It also implements VFTransform, for transformations of vectorfields.
• Frechet is a simple package implementing a multivariate derivative operator
• Taylor implements a multivariate Taylor expansion
• Ideal implements some important algorithms in computational algebraic geometry

Installation Instructions

Install the files in the addons package into a directory where Mathematica can find them. For example, my Mathematica installation is in

/usr/local/apps/mathematica/

so I put the files in

/usr/local/apps/mathematica/AddOns/Applications

If you don't have root access, put them in another directory, such as

$HOME/.Mathematica/Applications

then set the Mathematica $Path variable so the kernel can find them. For example, to alert Mathematica to the files in the directory $HOME/share/math, put the following line in the $HOME/.Mathematica/Kernel/init.m file:

$Path = Append[$Path, ToFileName[{$HomeDirectory, "share", "math"}]];

In the file init.m included with this distribution is a series of DeclarePackage declarations which, if you wish, can also be put into the .Mathematica/(VERSION)/Kernel/init.m file to autoload the packages.

Enjoy!
