Graded cluster algebras

WebIt is shown that many results on cluster algebras (the Laurent phenomenon, the classification of finite-type cluster algebras) extend to the quantum case. The important open problem is to show that quantum cluster monomials have non-negative coefficients. The paper under review deals with skew-symmetric acyclic quantum cluster algebras. The

Classification of graded cluster algebras generated by rank 3 …

WebWe then study gradings for finite type cluster algebras without coefficients, giving a full classification. Translating the definition suitably again, we obtain a notion of multi-grading for (generalised) cluster categories. This setting allows us to prove additional properties of graded cluster algebras in a wider range of cases. WebIn this section, we consider two constructions that produce graded quantum cluster algebra structures on skew-Laurent extensions of a given graded quantum cluster algebra. The … 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 ... fix the fundamentals in your core bank
