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 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.
