A cluster expansion formula ( case)
Ralf Schiffler
We consider the Ptolemy cluster algebras, which are cluster algebras of finite type (with non-trivial coefficients) that have been described by Fomin and Zelevinsky using trian…

A geometric model for cluster categories of type
Ralf Schiffler
We give a geometric realization of cluster categories of type using a polygon with vertices and one puncture in its center as a model. In this realization, the indecompos…

Cluster-tilted algebras as trivial extensions
Ibrahim Assem, Thomas Brüstle, Ralf Schiffler
Given a finite dimensional algebra (over an algebraically closed field) of global dimension at most two, we define its relation-extension algebra to be the trivial extension $C…
