研究了真实的阿贝尔域中某些分圆数集合之间的伽罗瓦关系。在一类情况下,这些关系的伽罗瓦生成元的一个完整的集合被确定。这些结果被用来研究[So]中引入的分圆p-单位群。特别是,后者被证明是伽罗瓦同构的一组分圆数。
We study Galois relations between certain sets of cyclotomic numbers in real abelian fields. In one class of cases, a complete set of Galois generators for these relations is determined. These results are used to study the group of cyclotomic p-units introduced in [So]. In particular, the latter is shown to be Galois isomorphic to the group of cyclotomic numbers.
