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 ... WebIn the cluster algebra literature, the notion of a graded cluster algebra has been implicit since the origin of the subject. In this work, we wish to bring this aspect of cluster …

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 ... WebSep 27, 2013 · A categorification of Grassmannian cluster algebras. We describe a ring whose category of Cohen–Macaulay modules provides an additive categorification of the cluster algebra structure on the homogeneous coordinate ring of the Grassmannian of k ‐planes in n ‐space. More precisely, there is a cluster character defined on the category … ipl 2022 csk players list
