Abstract
Let be a commutative Noetherian ring, an element of , and a nonzero finitely generated -module. We study the nonvanishing of and we give some conditions which guarantee that this is the case. In particular, we show that over a Noetherian local ring , for an ideal of , if , then for each , we have .
