Recollements and homological dimensions
Yongyun Qin
We investigate the behavior of the homological dimensions under recollements of derived categories of algebras. In particular, we establish a series of new bounds among the selfinj…

Jordan-Hölder theorems for derived categories of derived discrete algebras
Yongyun Qin
For any positive integer , -derived-simple derived discrete algebras are classified up to derived equivalence. Furthermore, the Jordan-Hölder theorems for all kinds of derive…
