On the global and \nabla-filtration dimensions of quasi-hereditary algebras
Karin Erdmann, Alison E. Parker
In this paper we consider how the \nabla-, Δ- and global dimensions of a quasi-hereditary algebra are interrelated. We first consider quasi-hereditary algebras with simple preservi…
Representation theory of the Drinfel'd doubles of a family of Hopf algebras
K. Erdmann, E. L. Green, N. Snashall +1
We investigate the Drinfel'd doubles of a certain family of Hopf algebras. We determine their simple modules and their indecomposable projective modules, and we obtain…
Modular Lie powers and the Solomon descent algebra
Karin Erdmann, Manfred Schocker
Let be an -dimensional vector space over an infinite field of prime characteristic , and let denote the -th homogeneous component of the free Lie algebra…
Support varieties for selfinjective algebras
Karin Erdmann, Miles Holloway, Nicole Snashall +2
Support varieties for any finite dimensional algebra over a field were introduced by Snashall-Solberg using graded subalgebras of the Hochschild cohomology. We mainly study these v…
