Vector invariants of permutation groups in characteristic zero

Fabian Reimers, Müfit Sezer

We consider a finite permutation group acting naturally on a vector space $V$ over a field $k$ . A well known theorem of Göbel asserts that the corresponding ring of invariants…

Separating Invariants for Two Copies of the Natural $S_{n}$ -Action

Fabian Reimers

This note provides a set of separating invariants for the ring of vector invariants $K [V^{2}]^{S_{n}}$ of two copies of the natural $S_{n}$ -representation $V = K^{n}$ over a field of chara…
