Group actions on polynomial rings

Peter Symonds (University of Manchester)

Wednesday 4th February, 2009 16:00-17:00 Mathematics Building, room 214


We consider a group acting on a polynomial ring over a finite field and try and understand the ring as a module for the group. After looking at some examples we formulate a Structure Theorem and show how it can be used to prove some conjectures in invariant theory.
