"On Cohen-Macaulayness
of Ideals in Invariant Rings"
By
Abstract: We investigate the presence of Cohen-Macaulay
ideals in invariant rings and show that an ideal in the invariant ring
corresponding to a modular representation of a $p$-group is not Cohen-Macaulay
unless the invariant ring itself is. (This is joint
with M. Kolhs.)
