Lattice structure in cluster algebra of finite type and non-simply-laced Ingalls-Thomas bijection

Abstract

In this paper, we demonstrate that the lattice structure of a set of clusters in a cluster algebra of finite type is anti-isomorphic to the torsion lattice of a certain Geiss-Leclerc-Schröer (GLS) path algebra and to the $c$-Cambrian lattice. We prove this by explicitly describing the exchange quivers of cluster algebras of finite type. Specifically, we prove that these quivers are anti-isomorphic to those formed by support $\tau$-tilting modules in GLS path algebras and to those formed by $c$-clusters consisting of almost positive roots.

34 pages, adding important remarks on previous studies (Remark 3.10 and Remark 8.20). In my comment on the 5th version, I described Remark 3.10 and Remark 8.20 as "critical remark on previous studies," but I did not mean anything negative about the previous studies. It was an error in my choice of English expression
