Some coefficients of rank 2 cluster scattering diagrams
arXiv:2507.21916
Abstract
The purpose of this paper is to translate the expression of rank 2 cluster scattering diagrams via dilogarithm elements into via formal power series. As a corollary, we prove some conjectures introduced by Thomas Elgin, Nathan Reading, and Salvatore Stella.
