PerMuVAR -- a MuPAD library for invariants of permutation groups
PerMuVAR is an open source library for the
computer algebra system MuPAD for
computing in invariant rings of permutation groups. The purpose it to
study (at least partially) permutation groups that are too big to be
treated by general invariant theory software. The main design goals
are the following:
- Predictability (algorithms based only on linear algebra, no
Gröbner basis computations);
- Reusability and extensibility (object oriented programming);
- Efficiency (Use of special properties of permutation groups;
use of external specialized libraries for critical sections).
PerMuVAR can use the C++ library GLIP to speedup the expensive
isomorphism-related computations. The sources of GLIP are included in
the distribution.
PerMuVAR should be fairly easy to install. If you experience any
problem, or just want to give it a try, you can also ask for an
account on the machines of the centre of resources for
computer algebra MEDICIS, where it's installed.
