On solvability of the first Hochschild cohomology of a finite-dimensional algebra
Florian Eisele, Theo Raedschelders
For an arbitrary finite-dimensional algebra , we introduce a general approach to determining when its first Hochschild cohomology , considered as a Lie algebra, i…
A reduction theorem for -rigid modules
Florian Eisele, Geoffrey Janssens, Theo Raedschelders
We prove a theorem which gives a bijection between the support -tilting modules over a given finite-dimensional algebra and the support -tilting modules over , where…
The representation theory of noncommutative
Theo Raedschelders, Michel Van den Bergh
In our companion paper "The Manin Hopf algebra of a Koszul Artin-Schelter regular algebra is quasi-hereditary" we used the Tannaka-Krein formalism to study the universal coacting H…
The Manin Hopf algebra of a Koszul Artin-Schelter regular algebra is quasi-hereditary
Theo Raedschelders, Michel Van den Bergh
For any Koszul Artin-Schelter regular algebra A, we consider a version of the universal Hopf algebra aut(A) coacting on A, introduced by Manin. To study the representations (i.e. f…
