Abstract
Let be a commutative Noetherian ring, a finitely generated -module and be a non-negative integer. In this article, it is shown that there is a finitely generated submodule of such that for all if and only if there is a finitely generated submodule of such that for all . This generalizes Faltings' Local-global Principle for the finiteness of local cohomology modules (Faltings' in Math. Ann. 255:45-56, 1981). Also, it is shown that whenever is a homomorphic image of a Gorenstein local ring, then the invariants and are equal, for every finitely generated -module and for all ideals of with . As a consequence, we determine the least integer where the local cohomology module is not minimax (resp. weakly laskerian).
