We consider generalizations of the definitions of one-dimensional tilting and cotilting modules which agree with the classical notions of tilting and cotilting modules of finite homological dimension.

โฆ Synopsis
Cotilting bimodules over arbitrary rings give rise to a theory which naturally generalizes Morita dualities in the setting of torsion theory. Here we study the case when the torsion theories cogenerated by a cotilting bimodule are hereditary.

This is the first of three papers that aim to bring the known theory of projective modules over a hereditary Noetherian prime ring R up to roughly the same level as the well-known commutative case, where R is a Dedekind domain. This first paper lays the foundations by introducing the notion of an in
Let R be a hereditary Noetherian prime ring. We determine a full set of invariants for the isomorphism class of any finitely generated projective R-module of uniform dimension at least 2. In particular we prove that P โ X โผ = Q โ X implies P โผ = Q whenever P has uniform dimension at least 2. Among t
We describe the structure of infinitely generated projective modules over hereditary Noetherian prime rings. The isomorphism invariants are uniform dimension and ranks at maximal ideals. Infinitely generated projective modules need not be free. However, every uncountably generated projective module
