Special Note: Unusual day

A classic problem in invariant theory, often referred to as Hilbert's 14th problem, asks, when a group acts on a finitely generated commutative algebra by algebra automorphisms, whether the ring of invariants is still finitely generated. The question extends to finite generation of the cohomology algebra of a group. We'll present recent progress and generalizations with a stress on the case of a general base ring, keeping as a model Evens' statement for finite groups.
