ATTACHED PRIMES OF THE TOP GENERALIZED LOCAL COHOMOLOGY MODULES

摘要

Let .R; m/ be a commutative Noetherian local ring, let I be an ideal of R and let M and N be finitelyngenerated R-modules. Assume that pd.(M)=d <∞, dim N ＝ n <∞. First, we give the formula for thenattached primes of the top generalized local cohomology module HdCnnIn.M; N/; later, we prove that ifnAtt.HdCnnIn.M; N// D Att.HdCnnJ .M; N//, then HdCnnIn.M; N/ D HdCnnJ .M; N/.
