A combinatorial characterisation of d-Koszul and (D,A)-stacked monomial algebras that satisfy (Fg)
Ruaa Jawad, Nicole Snashall, Rachel Taillefer
Condition (Fg) was introduced in [6] to ensure that the theory of support varieties of a finite dimensional algebra, established by Snashall and Solberg, has some similar propertie…
Koszul calculus of preprojective algebras
Roland Berger, Rachel Taillefer
We show that the Koszul calculus of a preprojective algebra, whose graph is distinct from A and A, vanishes in any (co)homological degree . Moreover, its (higher) co…
First Hochschild cohomology group and stable equivalence classification of Morita type of some tame symmetric algebras
Rachel Taillefer
We use the dimension and the Lie algebra structure of the first Hochschild cohomology group to distinguish some algebras of dihedral, semi-dihedral and quaternion type up to stable…
Stable Green ring of the Drinfeld doubles of the generalised Taft algebras (corrections and new results)
Karin Erdmann, Edward Green, Nicole Snashall +1
We return to the fusion rules for the Drinfeld double of the duals of the generalised Taft algebras that we studied in [9]. We first correct some proofs and statements in [9] that…
Hochschild cohomology of relation extension algebras
Ibrahim Assem, M. Andrea Gatica, Ralf Schiffler +1
Let be the split extension of a finite dimensional algebra by a --bimodule . We define a morphism of associative graded algebras $φ^*:\HH^*(B)\rightarrow \HH^*(C)$…
The Ext algebra of a Brauer graph algebra
Edward L Green, Sibylle Schroll, Nicole Snashall +1
In this paper we study finite generation of the Ext algebra of a Brauer graph algebra by determining the degrees of the generators. As a consequence we characterize the Brauer grap…
