摘要

Let R be a commutative Noetherian ring,a an ideal of R,and M a finitely generated R-module of finite Krull dimension n.We describe the (finite) sets Assn (H n/a (M))and Attr(H n/a(M)) of primes associated and attached to the highest local cohomologymodule H n/a (M) in terms of the local formal behaviour of a.
