Silting modules

LA Hügel, F Marks, J Vitória - … Mathematics Research Notices, 2016 - academic.oup.com
We introduce the new concept of silting modules. These modules generalize tilting modules
over an arbitrary ring, as well as support-tilting modules over a finite dimensional algebra …

Applications of cotorsion pairs

H Krause, Ø Solberg - Journal of the London Mathematical …, 2003 - Wiley Online Library
For an artin algebra Λ, cotorsion pairs are studied for the category Mod Λ of finitely
presented Λ‐modules and for the category Mod Λ of all Λ‐modules. It is shown that every …

Tilting modules and Gorenstein rings

LA Hügel, D Herbera, J Trlifaj - 2006 - degruyter.com
We apply tilting theory to study modules of finite projective dimension. We introduce the
notion of finite and cofinite type for tilting and cotilting classes of modules, respectively …

Derived equivalence induced by infinitely generated 𝑛-tilting modules

S Bazzoni, F Mantese, A Tonolo - Proceedings of the American …, 2011 - ams.org
Let $ T_R $ be a right $ n $-tilting module over an arbitrary associative ring $ R $. In this
paper we prove that there exists an $ n $-tilting module $ T'_R $ equivalent to $ T_R $ which …

[PDF][PDF] Infinite dimensional tilting modules and cotorsion pairs

J Trlifaj - LONDON MATHEMATICAL SOCIETY LECTURE NOTE …, 2007 - Citeseer
However, some aspects of the classical theory can be extended to infinitely generated
modules over arbitrary rings. In this paper, we will consider such an aspect: the relation of …

[HTML][HTML] Silting modules and ring epimorphisms

LA Hügel, F Marks, J Vitória - Advances in Mathematics, 2016 - Elsevier
There are well-known constructions relating ring epimorphisms and tilting modules. The new
notion of silting module provides a wider framework for studying this interplay. To every …

Direct limits of modules of finite projective dimension

LA Hügel, J Trlifaj - Rings, Modules, Algebras, and Abelian …, 2004 - books.google.com
We describe in homological terms the direct limit closure of a class C of modules over a ring
R. We also determine the closure of the cotorsion pair=(A, B) cogenerated by C. As an …

Cotorsion pairs generated by modules of bounded projective dimension

S Bazzoni, D Herbera - arXiv preprint arXiv:0707.2026, 2007 - arxiv.org
We apply the theory of cotorsion pairs to study closure properties of classes of modules with
finite projective dimension with respect to direct limit operations and to filtrations. We also …
