Formal Modular Seminvariants
R. James Shank
Abstract: We construct a generating set for the ring of invariants
for the four and five dimensional indecomposable modular representations
of a cyclic group of prime order. We then observe that for the four
dimensional representation the ring of invariants is generated in degrees
less than or equal to 2p-3, and for the five dimensional
representation the ring of invariants is generated in degrees
less than or equal to 2p-2.
