Vanishing of Tor Over Complete Intersections
In this paper we are concerned with the vanishing of over
complete intersection rings. Building on results of C. Huneke, D. Jorgensen and
R. Wiegand, and, more recently, H. Dao, we obtain new results showing that good
depth properties on the -modules , and force the
vanishing of for all .Comment: 25 pages, to appear in the Journal of Commutative Algebr
Equivalences from tilting theory and commutative algebra from the adjoint functor point of view
We give a category theoretic approach to several known equivalences from
(classic) tilting theory and commutative algebra. Furthermore, we apply our
main results to establish a duality theory for relative Cohen-Macaulay modules
in the sense of Hellus, Schenzel, and Zargar.Comment: This is the final version (17 pages) to appear in the New York
