Cotorsion pairs in cluster categories of type
arXiv:1704.04019
Abstract
In this paper, we give a complete classification of cotorsion pairs in a cluster category of type via certain configurations of arcs, called -compact Ptolemy diagrams, in an infinite strip with marked points. As applications, we classify -structures and functorially finite rigid subcategories in , respectively. We also deduce Liu-Paquette's classification of cluster tilting categories of and Ng's classification of torsion pairs in the cluster category of type .
