Cluster characters for cluster categories with infinite-dimensional morphism spaces

By Pierre-Guy Plamondon


We prove the existence of cluster characters for Hom-infinite cluster categories. For this purpose, we introduce a suitable mutation-invariant subcategory of the cluster category. We sketch how to apply our results in order to categorify any skew-symmetric cluster algebra. More applications and a comparison to Derksen-Weyman-Zelevinsky’s results will be given in a future paper
