Contraderived categories of CDG-modules
L Positselski, J Stovicek - arXiv preprint arXiv:2401.07021, 2024 - arxiv.org
For any CDG-ring $ B^\bullet=(B^*, d, h) $, we show that the homotopy category of graded-
projective (left) CDG-modules over $ B^\bullet $ is equivalent to the quotient category of the …

Exact DG-categories and fully faithful triangulated inclusion functors
L Positselski - arXiv preprint arXiv:2110.08237, 2021 - arxiv.org
We construct an" almost involution" assigning a new DG-category to a given one, and use
this construction in order to recover, say, the abelian category of graded modules over the …

Reflexivity and Hochschild Cohomology
I Goodbody - arXiv preprint arXiv:2403.09299, 2024 - arxiv.org
Reflexive DG-categories were defined by Kuznetsov and Shinder as generalisations of
smooth and proper DG-categories. Over a perfect field, they include all projective schemes …

Homotopy Category of Cotorsion Flat Representations of Quivers
H Eshraghi - Mathematics Interdisciplinary Research, 2020 - mir.kashanu.ac.ir
Recently in [10], it was proved that over any ring R, there exists a complete cotorsion pair
(Kp (Flat-R); K (dg-CotF-R)) in K (Flat-R), the homotopy category of complexes of flat R …

Sheaves of categories with local actions of Hochschild cochains
D Beraldo - Compositio Mathematica, 2019 - cambridge.org
The notion of Hochschild cochains induces an assignment from $\mathsf {Aff} $, affine DG
schemes, to monoidal DG categories. We show that this assignment extends, under …
