摘要
我们将簇代数中 y 变量(系数)的概念扩展到簇散射图(CSD)。相应地,我们将与簇模式中的周期相关的稀对数特性扩展为与 CSD 中的环相关的稀对数特性。我们证明,通过应用可能无限次的五边形特征,这些特征可以构造并简化为微不足道的特征。
DILOGARITHM IDENTITIES IN CLUSTER SCATTERING DIAGRAMS
We extend the notion of y-variables (coefficients) in cluster algebras to cluster scattering diagrams (CSDs). Accordingly, we extend the dilogarithm identity associated with a period in a cluster pattern to the one associated with a loop in a CSD. We show that these identities are constructed from and reduced to trivial ones by applying the pentagon identity possibly infinitely many times.
