Cluster structures via representation theory: cluster ensembles, tropical duality, cluster characters and quantisation
Jan E. Grabowski, Matthew Pressland
We develop a general theory of cluster categories, applying to a 2-Calabi-Yau extriangulated category and cluster-tilting subcategory satisfying only mi…
Cluster categories for completed infinity-gons I: Categorifying triangulations
İlke Çanakçı, Martin Kalck, Matthew Pressland
Paquette and Yıldırım recently introduced triangulated categories of arcs in completed infinity-gons, which are discs with an infinite closed set of marked points on their boundary…
Reduction of Frobenius extriangulated categories
Eleonore Faber, Bethany Rose Marsh, Matthew Pressland
We describe a reduction technique for stably 2-Calabi--Yau Frobenius extriangulated categories with respect to a functorially finite rigid subcategory .…
Extriangulated ideal quotients, with applications to cluster theory and gentle algebras
Xin Fang, Mikhail Gorsky, Yann Palu +2
We extend results of Brüstle-Yang on ideal quotients of 2-term subcategories of perfect derived categories of non-positive dg algebras to a relative setting. We find a new interpre…
