Erratum to "Support varieties and representation type of small quantum groups"
Joerg Feldvoss, Sarah Witherspoon
Some of the general results in the paper require an additional hypothesis, such as quasitriangularity. Applications to specific types of Hopf algebras are correct, as some of these…
Support Varieties and Representation Type of Self-Injective Algebras
Joerg Feldvoss, Sarah Witherspoon
We use the theory of varieties for modules arising from Hochschild cohomology to give an alternative version of the wildness criterion of Bergh and Solberg: If a finite dimensional…
Support varieties and representation type of small quantum groups
Joerg Feldvoss, Sarah Witherspoon
In this paper we provide a wildness criterion for any finite dimensional Hopf algebra with finitely generated cohomology. This generalizes a result of Farnsteiner to not necessaril…
On the Cohomology of Modular Lie Algebras
Joerg Feldvoss
In this paper we establish a connection between the cohomology of a modular Lie algebra and its p-envelopes. We also compute the cohomology of Zassenhaus algebras and their minimal…
Injective Modules and Prime Ideals of Universal Enveloping Algebras
Joerg Feldvoss
In this paper we study injective modules over universal enveloping algebras of finite-dimensional Lie algebras over fields of arbitrary characteristic. Most of our results are deal…
Existence of triangular Lie bialgebra structures II
Joerg Feldvoss
We characterize finite-dimensional Lie algebras over an arbitrary field of characteristic zero which admit a non-trivial (quasi-) triangular Lie bialgebra structure.
