On regular monomorphisms in weakly locally presentable categories

open access: yesJournal of Pure and Applied Algebra, 1997
\textit{J. Adámek}, \textit{H. Hu} and the reviewer [J. Pure Appl. Algebra 107, No. 1, 1-8 (1996; Zbl 0852.18002)] showed that in a \(\kappa\)-accessible category \({\mathcal A}\) with pushouts, regular monomorphisms are closed under \(\kappa\)-directed colimits in \({\mathcal A}^2\) (the arrow category of \({\mathcal A})\), which implies that \(\kappa\

Covers, envelopes, and cotorsion theories in locally presentable abelian categories and contramodule categories

open access: yesJournal of Algebra, 2017
We prove general results about completeness of cotorsion theories and existence of covers and envelopes in locally presentable abelian categories, extending the well-established theory for module categories and Grothendieck categories. These results are then applied to the categories of contramodules over topological rings, which provide examples and ...

Are all cofibrantly generated model categories combinatorial?

open access: yes, 2009
G. Raptis has recently proved that, assuming Vop\v{e}nka's principle, every cofibrantly generated model category is Quillen equivalent to a combinatorial one.
