Quivers with relations and cluster tilted algebras
Philippe Caldero, Frederic Chapoton, Ralf Schiffler
Cluster algebras were introduced by S. Fomin and A. Zelevinsky in connection with dual canonical bases. To a cluster algebra of simply laced Dynkin type one can associate the clust…
Cluster algebras as Hall algebras of quiver representations
Philippe Caldero, Frederic Chapoton
Recent articles have shown the connection between representation theory of quivers and the theory of cluster algebras. In this article, we prove that some cluster algebras of type…
Sur le nombre de reflexions pleines dans les groupes de Coxeter finis
Frederic Chapoton
On etudie divers aspects d'une formule qui compte les reflexions pleines dans les groupes de Coxeter finis. ***** We study several points about a formula which counts reflexions in…
Left cells and constructible representations
Meinolf Geck
We consider the partition of a finite Coxeter group into left cells with respect to a weight function . In the equal parameter case, Lusztig has shown that the representatio…
