The theory of j-operators with application to (weak) liftings of DG modules
Saeed Nasseh, Maiko Ono, Yuji Yoshino
A major part of this paper is devoted to an in-depth study of j-operators and their properties. This study enables us to obtain several results on liftings and weak liftings of DG…
Generation in singularity categories of hypersurfaces of countable representation type
Tokuji Araya, Kei-ichiro Iima, Maiko Ono +1
The Orlov spectrum and Rouquier dimension are invariants of a triangulated category to measure how big the category is, and they have been studied actively. In this paper, we inves…
An Auslander-Reiten principle in derived categories
Maiko Ono, Yuji Yoshino
We give a principle in derived categories, which lies behind the classical Auslander-Reiten duality and its generalized version by Iyama and Wemyss. We apply the principle to show…
A lifting problem for DG modules
Maiko Ono, Yuji Yoshino
Let be an extended DG algebra by the adjunction of variable of positive even degree , and let be a semi-free DG -module that is assumed to be bounded…
