摘要
对 Noether -代数 ,存在典范包含 ,且像中每个元素满足某相容条件。若像与所有相容元素之集重合,则称 为相容的。例如,对 Dynkin 箭图 与含域的交换 Noether 环 ,路径代数 是相容的。本文证明当 为扩展 Dynkin 箭图且 为 Dedekind 整环或二维 Noether 半局部正规环时, 是相容的。

备注
20 pages, we have improved many results, in particular, (i) using results from our recent paper arXiv:2504.02371, we succeeded in removing the assumption that R contains a field in main Theorem 1.2, (ii) we provided an explicit description of the map r_{pq} for the Kronecker quiver over a Dedekind domain in Section 6
