Categorification of the Fibonacci numbers using representations of quivers
Philipp Fahr, Claus Michael Ringel
In a previous paper we have presented a partition formula for the even-index Fibonacci numbers using the preprojective representations of the 3-Kronecker quiver and its universal c…
On the representation dimension of artin algebras
Claus Michael Ringel
The representation dimension of an artin algebra as introduced by M.Auslander in his Queen Mary Notes is the minimal possible global dimension of the endomorphism ring of a generat…
Cluster-additive functions on stable translation quivers
Claus Michael Ringel
Additive functions on translation quivers have played an important role in the representation theory of finite dimensional algebras, the most prominent ones are the hammock functio…
The finitistic dimension of algebras with a directed stratification]
Karsten Dietrich
We introduce the notion of a directed stratification for a finite-dimensional algebra. For algebras that admit such a stratification we characterise the projective resolutions of f…
