We construct a triangulated category CA associated to A which, if A is hereditary, is triangle equivalent to the cluster category of A. When CA is Hom-finite, we prove that it is 2-CY and endowed with a canonical cluster-tilting object. chris hein strings compact free download https://shopmalm.com

WebSep 28, 2010 · The algebra possesses four bases, a Poincaré–Birkhoff–Witt basis, a canonical basis, and their duals. We prove recursions for dual canonical basis elements. The recursions imply that every cluster variable in is the specialization of the dual of an appropriate canonical basis element. WebA cluster algebra A of rank n is a subalgebra of an ambient field F isomorphic to a field of rational functions in n variables. Each cluster algebra comes equipped with a distinguished set of generators called cluster variables; this set is a union of overlapping algebraically independent n-subsets of F called clusters.
