The proposed research builds upon PIs' previous collaboration on applications of Poisson geometry to cluster algebras. In the current project we will undertake a systematic study of multiple cluster structures in coordinate rings of a number of varieties of importance in algebraic geometry, representation theory and mathematical physics and study an interaction between corresponding cluster algebras. Important examples include simple Lie groups, homogeneous spaces, configuration spaces of points, and are related to discrete and continuous integrable systems. The problems to be considered include cluster structures on simple Lie groups compatible with Poisson-Lie structures associated with the Belavin-Drinfeld classification, inverse problems for directed nets on surfaces of higher genus, continuous limits for directed networks with applications to moduli spaces of flat connections and growth rate classification of cluster algebras.The rapid development of the cluster algebra theory in recent years revealed relations between cluster algebras and a variety of areas including, among others, commutative and non-commutative algebraic geometry, quiver representations and Teichmuller theory. The proposed research is linked to the development of undergraduate and graduate courses and research projects. Synergistic activities are planned with the goal to promote inter-institutional and inter-departmental cooperation, to attract graduate students from underrepresented groups and with diverse educational backgrounds, and, through a community outreach, at the early exposure of high school students to mathematical research.

拟议的研究建立在 PI 先前在泊松几何在聚类代数应用方面的合作基础上。在当前的项目中，我们将对代数几何、表示论和数学物理中多种重要的坐标环中的多重簇结构进行系统研究，并研究相应簇代数之间的相互作用。重要的例子包括简单的李群、齐次空间、点的配置空间，并且与离散和连续可积系统相关。要考虑的问题包括与 Belavin-Drinfeld 分类相关的 Poisson-Lie 结构兼容的简单李群上的簇结构、更高属表面上有向网络的反演问题、有向网络的连续极限及其在平面连接模空间中的应用近年来，簇代数理论的快速发展揭示了簇代数与许多领域（包括交换性和非交换性等）之间的关系。代数几何、箭袋表示和 Teichmuller 理论。拟议的研究与本科生和研究生课程及研究项目的开发相关。协同活动的目的是促进机构间和部门间的合作，吸引来自代表性不足群体和具有不同教育背景的研究生，并通过社区外展，让高中生尽早接触数学研究。
