Homological Invariants of Left and Right Serial Quiver Algebras
Ruoyu Guo
We investigate the relationship between the delooping level (dell) and the finitistic dimension of left and right serial quiver algebras. These 2-syzygy finite algebras have finite…

Symmetry of Derived Delooping Level
Ruoyu Guo
The finitistic dimension conjecture is closely connected to the symmetry of the finitistic dimension. Recent work indicates that such connection extends to one of its upper bounds,…

Derived delooping levels and finitistic dimension
Ruoyu Guo, Kiyoshi Igusa
In this paper, we develop new ideas regarding the finitistic dimension conjecture, or the findim conjecture for short. Specifically, we improve upon the delooping level by introduc…
