A corollary to the Evans-Griffith Syzygy theorem
Adic-completion and some dual homological results.
Let a be an ideal of a commutative ring A. There is a kind of duality between the left derived functors Ui a of the a-adic completion functor, called local homology functors, and the local cohomology functors Ha i. Some dual results are obtained for these Ui a, and also inequalities involving both local homology and local...
