“Vector invariants of a permutation group over characteristic zero”<\/p>\n
Abstract: We consider a finite permutation group acting naturally on a vector space V over a field k. A well known theorem of G\u00f6bel asserts that the corresponding ring of invariants k[V]G is generated by invariants of degree at most dim V choose 2. We point out that if the characteristic of k is zero then the top degree of the vector coinvariants k[mV]G is also bounded above by n choose 2 implying that G\u00f6bel’s bound almost holds for vector invariants as well in characteristic zero.
