Modules of constant Jordan type over quantum complete intersections
Petter Andreas Bergh, Karin Erdmann, David A. Jorgensen
We initiate the study of modules of constant Jordan type for quantum complete intersections, and prove a range of basic properties. We then show that for these algebras, constant J…

Ext-finite modules for weakly symmetric algebras with radical cube zero
Karin Erdmann
Assume is weakly symmetric, indecomposable, with radical cube zero and radical square non-zero. We show that such algebra of wild representation type does not have a non-projec…
