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.

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.

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.
