摘要

我们给出了互反广义簇代数的广义簇变体和广义簇散射图的构造，后者是由Chekhov和Shapiro定义的。这些构造类似于Gross、Hacking、Keel和Kontsevich工作中为普通簇代数给出的结构。由于这些构造，我们也能够构造广义簇代数的θ函数，同样是在倒数的情况下，并证明了它们的一些结构性质。

Cluster Scattering Diagrams and Theta Functions for Reciprocal Generalized Cluster Algebras

We give a construction of generalized cluster varieties and generalized cluster scattering diagrams for reciprocal generalized cluster algebras, the latter of which were defined by Chekhov and Shapiro. These constructions are analogous to the structures given for ordinary cluster algebras in the work of Gross, Hacking, Keel, and Kontsevich. As a consequence of these constructions, we are also able to construct theta functions for generalized cluster algebras, again in the reciprocal case, and demonstrate a number of their structural properties.
