The finitistic dimension of an Artin algebra with radical square zero
Vincent Gélinas
We investigate the inequality between the finitistic dimension and the delooping level of an Artin algebra , and whether equality…

The depth, the delooping level and the finitistic dimension
Vincent Gélinas
We investigate two invariants of Noetherian semiperfect rings, namely the depth and a new invariant we call the "delooping level". These give lower and upper bounds for the finitis…
