Abstract:
In
this paper we present a new approach to Grothendieck duality over
commutative rings. Our approach is based on the idea of rigid
dualizing complexes, which was introduced by Van den Bergh in the
context of noncommutative algebraic geometry. The method of rigidity
was modied to work over general commutative base rings in our paper
[YZ5]. In the present paper we obtain many of the important local
features of Grothendieck duality, yet manage to avoid lengthy and
difficult compatibility verifications. Our results apply to
essentially finite type algebras over a regular noetherian finite
dimensional base ring, and hence are suitable for arithmetic rings.
In the sequel paper [Ye4] these results will be used to construct and
study rigid dualizing complexes on schemes.
