… Morita's important theory of equivalences and dualities for categories of modules over rings.
Given the key roles projective and injective modules play in this book, the reader will be well-…

… of strongly (n, d)-injective modules to characterize n-coherent rings. For a right perfect ring
R, it is shown that R is right n-coherent if and only if every right R-module has a strongly (n, d)-…

… Relationships between homological dimensions of Noetherian rings and duality conditions
on finitely generated modules have been studied in [1], [4], In this paper we consider …

… by weak injective modules. The main purpose … coherent rings to any rings. In Section 2, we
introduced the notion of Gorenstein weak injective modules in terms of weak injective modules…

… rings (or projective curves) even the categories of modules (respectively, of vector bundles)
are wild. In both cases the description reduces to a special class of matrix problems (“…

… model structures to categories of rings, algebras, and modules. This includes, but is not
limited to, each of the new theories of ring spectra. One model for structured ring spectra is given …

… n-semihereditary rings and von Neumann regular rings are obtained. Throughout this
article, R is an associative ring with identity, and all modules are unitary. Let N be a left R-module …
