Abstract
Let be a short Artin local ring (i.e., and ). Assume is not a hypersurface ring. We show there exists such that if is any finitely generated module with bounded betti-numbers then divides , the length of . If is not a complete intersection then there exists such that if is any module with then divides for all (here denotes the -syzygy of ).
