The derived Hall algebra of a graded gentle one-cycle algebra I: the triangle structure

Hui Chen, Dong Yang

Under a mild condition, the perfect derived category and the finite-dimensional derived category of a graded gentle one-cycle algebra are described as twisted root categories of ce…

From objects finitely presented by a rigid object in a triangulated category to 2-term complexes

Dong Yang

For a rigid object $M$ in an algebraic triangulated category $T$ , a functor pr $(M) \to H^{[- 1, 0]} (proj A)$ is constructed, which essentially takes an obje…

Classification of silted algebras for two quivers of Dynkin type $A_{n}$

Zongzhen Xie, Dong Yang, Houjun Zhang

In this paper, we give a complete classification of silted algebras for the quiver $A_{n}$ of type $A_{n}$ with linear orientation and for the qu…
