Reduction techniques for the derived delooping levels
Kaili Wu, Jiaqun Wei, Dajun Liu +1
The derived delooping level is a recently introduced homological invariant that provides an upper bound for the finitistic dimension of the opposite algebra. In this paper, we empl…

Degree-shifted derived invariance of derived delooping levels
Jiaqun Wei, Kaili Wu, Weiqing Cao
Gélinas introduced the delooping level of an Artin algebra as a homological invariant that bounds the big finitistic dimension of the opposite algebra. A natural question is whethe…
