Abstract: Let be a commutative noetherian local ring and be a finitely generated -module of infinite projective dimension. It is well-known that the depths of the syzygy modules of eventually stabilize to the depth of . In this paper, we investigate the conditions under which a similar statement can be made regarding dimension. In particular, we show that if is equidimensional and the Betti numbers of are eventually non-decreasing, then the dimension of any sufficiently high syzygy module of coincides with the dimension of .
