Web4 N. Hanihara Theorem 1.2 (Theorem 4.6(4)). Let R be a graded bimodule (𝑑+1)-CY algebra of a-invariant a satisfying (R0) and (R1). Then the subcategory add{𝑅(−𝑖)[𝑖] 𝑖∈Z}⊂qperZ𝑅is a (𝑑+𝑎)-cluster tilting subcategory. For example, by setting R to be the polynomial ring with standard positive grading, we deduce that the derived category of coherent sheaves over the ...

WebTheorem 1. Let Rbe an artinian standard graded algebra and M a nitely gen-erated graded R-module, generated in a single degree. If Exti R (M;M) = 0 = Exti R (M;R) for all i>0, then Mis free. Our second result concerns Gorenstein rings. The hypothesis of the following theorem is known to be satis ed by generic standard graded Gorenstein algebras WebMar 1, 2014 · In this work, our main aim is to bring these three parts of cluster algebra theory together, to study graded quantum cluster algebras of infinite rank. More specifically, Assem, Dupont and Schiffler ([1]) have introduced a category Clus of rooted cluster algebras. The objects of Clus are pairs consisting of a cluster algebra and a …
Web3 Multi-graded seeds and cluster algebras The natural definition for a multi-graded seed is as follows. Definition 3.1 A multi-graded seed is a triple (x,B,G) such that (a) (x = (X1,...,Xr),B) is a seed of cardinality r and (b) G is an r ×d integer matrix such that BT G = 0. From now on, we use the term “graded” to encompass multi-graded ... WebSep 4, 2024 · The article concerns the existence and uniqueness of quantisations of cluster algebras. We prove that cluster algebras with an initial exchange matrix of full rank admit a quantisation in the sense of Berenstein-Zelevinsky and give an explicit generating set to construct all quantisations.
