A note on spherical algebras
Karin Erdmann, Adam Skowyrski
We classify tame symmetric algebras of period four which are closely related to the spherical algebras introduced in [7]. This note provides a classification in the special case wh…

Monomial arrow removal and the finitistic dimension conjecture
Karin Erdmann, Odysseas Giatagantzidis, Chrysostomos Psaroudakis +1
In this paper, we introduce the monomial arrow removal operation for bound quiver algebras, and show that it is a novel reduction technique for determining the finiteness of the fi…

On Krull-Gabriel dimension of weighted surface algebras
Karin Erdmann, Alicja Jaworska-Pastuszak, Grzegorz Pastuszak
We determine the Krull-Gabriel dimension of weighted surface algebras, a class of algebras which recently appeared in the context of classification of tame symmetric periodic algeb…
