Invariant Theory
New Features:
- Algorithms have been implemented for computing invariant rings of
reductive groups. Derksen's algorithm for reductive groups is among
those implemented.
- Algorithms have been implemented for computing invariant fields
(these include Derksen's algorithm).
- A new algorithm of G. Kemper for computing the secondary invariants
in the non-modular case has been implmented. This algorithm is very
much faster than the previous one.
- The primary invariants algorithm has been improved by
use of Faugere F4 techniques.
