Graded cluster algebras - Springer

Webgraded cluster algebras are particularly important when studying cluster algebra structures on the (multi-)homogeneous coordinate rings of projective varieties, as one naturally expects. Another important generalisation concerns the quantization of cluster algebras, that is, a noncommutative version of the theory. WebNov 4, 2024 · We also study the connection between cluster algebras with universal coefficients and cluster complexes. We show that for a full rank positively graded cluster algebra $\mathcal{A}$ of geometric and finite cluster type, the cluster algebra $\mathcal{A}^{\mathrm{univ}}$ with universal coefficients may be recovered as the … http://arxiv-export3.library.cornell.edu/pdf/1510.04109v1 greeba road wythenshawe
