Cluster Theories and Cluster Structures of Type A
Abstract
In the present paper we examine the relationship between several type A cluster theories and structures. We define a 2D geometric model of a cluster theory, which generalizes cluster algebras from surfaces, and encode several existing type A cluster theories into a 2D geometric model. We review two other cluster theories of type A. Then we introduce an abstraction of cluster structures. We prove two results: the first relates several existing type A cluster theories and the second relates some of these cluster structures using the new abstraction.
