An equivalence linking CM-types and
Charley Cummings, Sira Gratz, Ellen Kirkman +3
We show that, for a specific grading, the stable categories of graded maximal Cohen-Macaulay modules over hypersurfaces of type and are equivalent.

Homological regularities and concavities
Ellen Kirkman, Robert Won, James J. Zhang
This paper concerns homological notions of regularity for noncommutative algebras. Properties of an algebra are reflected in the regularities of certain (complexes of) -modu…

Some Artin-Schelter Regular Algebras From Dual Reflection Groups and their Geometry
Peter Goetz, Ellen E. Kirkman, W. Frank Moore +1
Let be a group coacting on an Artin-Schelter regular algebra homogeneously and inner-faithfully. When the identity component is also Artin-Schelter regular, providing…
