We consider the invariant ring for an indecomposable representation of a cyclic group of order p 2 over a field of characteristic p. We describe a set of -algebra generators of this ring of invariants, and thus derive an upper bound for the largest degree of an element in a minimal generating set for the ring of invariants. This bound, as a polynomial in p, is of degree two. © 2008 Springer-Verlag.
