[HTML][HTML] Classifying exact categories via Wakamatsu tilting
H Enomoto - Journal of Algebra, 2017 - Elsevier
Using the Morita-type embedding, we show that any exact category with enough projectives
has a realization as a (pre) resolving subcategory of a module category. When the exact …

Monobrick, a uniform approach to torsion-free classes and wide subcategories
H Enomoto - Advances in Mathematics, 2021 - Elsevier
For a length abelian category, we show that all torsion-free classes can be classified by

Quasi-tilting modules and counter equivalences
R Colpi, G D'Este, A Tonolo - Journal of Algebra, 1997 - Elsevier
Given two ringsRandS, we study the category equivalences T⇄ Y, where T is a torsion class
ofR-modules and Y is a torsion-free class ofS-modules. These equivalences correspond to …

[HTML][HTML] On a characterization of (co) silting objects
S Breaz - Journal of Pure and Applied Algebra, 2024 - Elsevier
We prove that an object U in a triangulated category with coproducts is silting if and only if it
is a (weak) generator of the category, the orthogonal class U⊥> 0 contains U, and U⊥> 0 is …
