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 WebApr 16, 2024 · Categorification and the quantum Grassmannian. In \cite {JKS} we gave an (additive) categorification of Grassmannian cluster algebras, using the category $\CM (A)$ of Cohen-Macaulay modules for a certain Gorenstein order . In this paper, using a cluster tilting object in the same category $\CM (A)$, we construct a compatible pair , …
