“Group Actions on Polynomial Rings”
Peter
Symonds
(
ABSTRACT: We consider a group acting on a polynomial ring
over a finite field and describe a structure theorem that explains how the ring
behaves as a module for the group. There are several unexpected consequences,
in particular a bound on the degrees of the generators for the invariants that does
not depend on the group.
