Stasheff多面体与A_n型簇X簇的配位环

Stasheff polytopes and the coordinate ring of the cluster X-variety of type A_n

Linhui Shen

摘要:

我们定义Stasheff多面体在空间的热带点的集群A-品种。研究了簇X簇的标准基元素的乘积的支撑。我们证明了对于A_n型的簇X簇,这样的支撑是Stasheff多面体.

英文摘要:

We define Stasheff polytopes in the space of tropical points of cluster A-varieties. We study the supports of products of elements of canonical bases for cluster X-varieties. We prove that, for the cluster X-variety of type A_n, such supports are Stasheff polytopes.
