A Characteristic free approach to skew-gentle algebras
Yiping Chen
To each skew-gentle algebra, one can assign a gentle algebra in terms of combinatorial data. In order to relate the structures of the two algebras, we establish a homological epimo…
Singular equivalences and Auslander-Reiten conjecture
Yiping Chen, Wei Hu, Yongyun Qin +1
Auslander-Reiten conjecture, which says that an Artin algebra does not have any non-projective generator with vanishing self-extensions in all positive degrees, is shown to be inva…
Approximations, ghosts and derived equivalences
Yiping Chen, Wei Hu
Approximation sequences and derived equivalences occur frequently in the research of mutation of tilting objects in representation theory, algebraic geometry and noncommutative geo…
Derived equivalences between subrings
Yiping Chen
In this paper, we construct derived equivalences between two subrings of relevant -Auslander-Yoneda rings from an arbitrary short exact sequence in an abelian category. As a con…
Derived equivalences between matrix subrings and their applications
Yiping Chen
In this paper, we construct derived equivalences between matrix subrings. As applications, we calculate the global dimensions and the finitistic dimensions of some matrix subrings.…
Derived equivalences in n-angulated categories
Yiping Chen
In this paper, we consider -perforated Yoneda algebras for -angulated categories, and show that, under some conditions, -angles induce derived equivalences between the quo…
