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 WebJul 2, 2014 · Snake graphs appear naturally in the theory of cluster algebras. For cluster algebras from surfaces, each cluster variable is given by a formula whose terms are parametrized by the perfect matchings of a snake graph. In this paper, we continue our study of snake graphs from a combinatorial point of view. We advance the study of …

We start with an initial seed, consisting of a cluster of cluster variables along with additional data (usually in the form of a quiver) specifying how to mutate the seed to form new seeds. Clusters in these new seeds are created from the old cluster
