On the classification of higher Auslander algebras for Nakayama algebras

Dag Oskar Madsen, Rene Marczinzik, Gjergji Zaimi

We give new improved bounds for the dominant dimension of Nakayama algebras and use those bounds to give a classification of Nakayama algebras with simple modules that are high…

On bounds of homological dimensions in Nakayama algebras

Dag Oskar Madsen, Rene Marczinzik

Let be a Nakayama algebra with simple modules and a simple module of even projective dimension . Choose minimal such that a simple -module with projective dim…

Hochschild homology and trivial extensions

Petter Andreas Bergh, Dag Oskar Madsen

We prove that if an algebra is either selfinjective, local or graded, then the Hochschild homology dimension of its trivial extension is infinite.

Cohomological Comparison Theorem

Edward Green, Dag Madsen, Eduardo N. Marcos

If is an idempotent in a ring , then we find sufficient \linebreak conditions which imply that the cohomology rings $\oplus_{n\ge 0}Ext^n_Λ(Λ/{\br},Λ/{\br})$ and \linebreak…

Quasi-hereditary algebras and generalized Koszul duality

Dag Oskar Madsen

We present an easily applicable sufficient condition for standard Koszul algebras to be Koszul with respect to . If a quasi-hereditary algebra is Koszul with respect to ,…

Filtrations in abelian categories with a tilting object of homological dimension two

Bernt Tore Jensen, Dag Madsen, Xiuping Su

We consider filtrations of objects in an abelian category $\catA$ induced by a tilting object of homological dimension at most two. We define three disjoint subcategories with…
