On Gorenstein projective, injective and flat dimensions-a functorial description with applications
LW Christensen, A Frankild, H Holm - arXiv preprint math/0403156, 2004 - arxiv.org
Gorenstein homological dimensions are refinements of the classical homological
dimensions, and finiteness singles out modules with amenable properties reflecting those of …

Foxby equivalence over associative rings
H Holm, D White - Journal of Mathematics of Kyoto University, 2007 - projecteuclid.org
We extend the definition of a semidualizing module to general associative rings. This
enables us to define and study Auslander and Bass classes with respect to a semidualizing …

Support and adic finiteness for complexes
S Sather-Wagstaff, R Wicklein - Communications in Algebra, 2017 - Taylor & Francis
Let X be a chain complex over a commutative noetherian ring R, that is, an object in the
derived category 𝒟 (R). We investigate the small support and co-support of X, introduced by …

Duality and tilting for commutative DG rings
A Yekutieli - arXiv preprint arXiv:1312.6411, 2013 - arxiv.org
We consider commutative DG rings (better known as nonpositive strongly commutative

Finitistic dimensions over commutative DG-rings
We study the small and big finitistic projective, injective and flat dimensions over a non-
positively graded commutative noetherian DG-ring $ A $ with bounded cohomology. Our …

Rigid dualizing complexes over commutative rings
A Yekutieli, JJ Zhang - Algebras and representation theory, 2009 - Springer
In this paper we present a new approach to Grothendieck duality over commutative rings.
Our approach is based on the idea of rigid dualizing complexes, which was introduced by …

Compact DG modules and Gorenstein DG algebras
XF Mao, QS Wu - Science in China Series A: Mathematics, 2009 - Springer
When the base connected cochain DG algebra is cohomologically bounded, it is proved that
the difference between the amplitude of a compact DG module and that of the DG algebra is …
