Erick D. Rodriguez Bazan - Algorithms for fundamental equivariants and invariants
–
4 November 2020
In this talk, we offer algorithms to compute relevant sets of generators of equivariants modules, together with generators for the ring of invariants. We show how ideal interpolation can be applied to compute the generating invariants and equivariants of a reflection group. Given a set of primary invariants for any representation of a finite group, we apply interpolation algorithms to compute both a set of secondary invariants; and free bases of all fundamental equivariant modules. We propose a new algorithm to compute a set of generating invariants simultaneously to the generating equivariants.
