Cluster Algebras of Type A $_{\bf{2}}^{\bf {(1)}}$ [PDF]

Algebras and Representation Theory, 2011
In this paper we study cluster algebras \(\mathcal{A}\) of type \(A_2^{(1)}\). We solve the recurrence relations among the cluster variables (which form a T-system of type \(A_2^{(1)}\)). We solve the recurrence relations among the coefficients of \(\mathcal{A}\) (which form a Y-system of type \(A_2^{(1)}\)).
