Graded cluster algebras

WebJul 4, 2024 · Abstract. Let A be a path A∞ -algebra over a positively graded quiver Q: We prove that the derived category of A is triangulated equivalent to the derived category of kQ; which is viewed as a DG algebra with trivial differential. The main technique used in the proof is Koszul duality for DG algebras. Download to read the full article text. WebGraded seeds and graded quantum cluster algebras. Berenstein and Zelevinsky [3, Definition 6.5] have given a definition of graded quantum seeds, which give rise to module gradings but not algebra gradings. In what follows, we will have need of algebra gradings on quantum cluster algebras and so we now give a different definition of a graded ...

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 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 ... Webgraded cluster algebras are particularly important when studying cluster algebra structures on the (multi-)homogeneous coordinate rings of projective varieties, as one naturally expects. Another important generalisation concerns the quantization of cluster algebras, that is, a noncommutative version of the theory. greathouse of pizza casey
