"On Cohen-Macaulayness of Ideals in Invariant Rings"
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.)
