Triangulated Matlis equivalence
Abstract
This paper is a sequel to arXiv:1503.05523 and arXiv:1605.03934. We extend the classical Harrison-Matlis module category equivalences to a triangulated equivalence between the derived categories of the abelian categories of torsion modules and contramodules over a Matlis domain. This generalizes to the case of any commutative ring with a fixed multiplicative system such that the -module has projective dimension . The latter equivalence connects complexes of -modules with -torsion and -contramodule cohomology modules. It takes a nicer form of an equivalence between the derived categories of abelian categories when consists of nonzero-divisors or the -torsion in is bounded.
