Representation type of Borel-Schur algebras
Karin Erdmann, Ana Paula Santana, Ivan Yudin
In our previous work arXiv:1306.1770, we found all Borel-Schur algebra of finite representation type. In the present article, we determine which Borel-Schur algebras of infinite re…
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…
Higher Spherical Algebras
Karin Erdmann, Andrzej Skowronski
We introduce and study higher spherical algebras, an exotic family of finite-dimensional algebras over an algebraically closed field. We prove that every such an algebra is derived…
Cohomology of some local selfinjective algebras
Karin Erdmann
We show that the cohomology for some 2-generated selfinjective algebras is finitely generated. This applies in particular to the algebras for in the classificatio…
Cluster tilting modules for mesh algebras
Karin Erdmann, Sira Gratz, Lisa Lamberti
We study cluster tilting modules in mesh algebras of Dynkin type, providing a new proof for their existence. In all but one case, we show that these are precisely the maximal rigid…
Weighted surface algebras: general version
Karin Erdmann, Andrzej Skowroński
We introduce general weighted surface algebras of triangulated surfaces with arbitrarily oriented triangles and describe their basic properties. In particular, we prove that all th…
