-angulated categories
Christof Geiss, Bernhard Keller, Steffen Oppermann
We define -angulated categories by modifying the axioms of triangulated categories in a natural way. We show that Heller's parametrization of pre-triangulations extends to pre-$…
Generic bases for cluster algebras and the Chamber Ansatz
Christof Geiß, Bernard Leclerc, Jan Schröer
Let Q be a finite quiver without oriented cycles, and let be the corresponding preprojective algebra. Let g be the Kac-Moody Lie algebra with Cartan datum given by Q, and let W…
Kac-Moody groups and cluster algebras
Christof Geiss, Bernard Leclerc, Jan Schröer
Let Q be a finite quiver without oriented cycles, let Λbe the associated preprojective algebra, let g be the associated Kac-Moody Lie algebra with Weyl group W, and let n be the po…
