Uniqueness of enhancements for derived and geometric categories

A Canonaco, A Neeman, P Stellari - Forum of Mathematics, Sigma, 2022 - cambridge.org
We prove that the derived categories of abelian categories have unique enhancements—all
of them, the unbounded, bounded, bounded above and bounded below derived categories …

Uniqueness of dg enhancements for the derived category of a Grothendieck category

A Canonaco, P Stellari - Journal of the European Mathematical Society, 2018 - ems.press
We prove that the derived category of a Grothendieck abelian category has a unique dg
enhancement. Under some additional assumptions, we show that the same result holds true …

Uniqueness of enhancement for triangulated categories

V Lunts, D Orlov - Journal of the American Mathematical Society, 2010 - ams.org
The paper contains general results on the uniqueness of a DG enhancement for triangulated
categories. As a consequence we obtain such uniqueness for the unbounded derived …

Generating the bounded derived category and perfect ghosts

S Oppermann, J Št'ovíček - Bulletin of the London Mathematical …, 2012 - academic.oup.com
We show, for a wide class of abelian categories relevant in representation theory and
algebraic geometry, that the bounded derived categories have no non-trivial strongly finitely …

Derived, coderived, and contraderived categories of locally presentable abelian categories

L Positselski, J Šťovíček - Journal of Pure and Applied Algebra, 2022 - Elsevier
For a locally presentable abelian category B with a projective generator, we construct the
projective derived and contraderived model structures on the category of complexes …

One-sided Grothendieck quotients

W Rump - Archiv der Mathematik, 2007 - Springer
We introduce one-sided thick subcategories C of an arbitrary preadditive category A and
define a quotient category A/C. When A is abelian, this concept specializes to …

Gorenstein cohomology in abelian categories

S Sather-Wagstaff, T Sharif, D White - Journal of Mathematics of …, 2008 - projecteuclid.org
We investigate relative cohomology functors on subcategories of abelian categories via
Auslander-Buchweitz approximations and the resulting strict resolutions. We verify that …

Exact completion and representations in abelian categories

J Rosický, EM Vitale - Homology, Homotopy and Applications, 2001 - projecteuclid.org
When the exact completion of a category with weak finite limits is a Mal'cev category, it is
possible to combine the universal property of the exact completion and the universal …
