Computing the invariant ring of a finite group

Thomas Hawes

Vol. 5 (2013), 15–19

We give an overview of a new package for Macaulay2 called InvariantRing, which contains tools for describing the invariant ring of finite group actions on polynomial rings in characteristic zero. We outline methods for computing primary and secondary invariants and compare the two algorithms that are implemented for computing primary invariants.
