关于数域Z_p扩张的泛范数和第一层

On universal norms and the first layers of Z_p-extensions of a number field

Abbas Movahhedi, Thong Nguyen Quang Do

摘要:

对于奇素数p和含有本原p次单位根单位根的数域F,我们用F的分圆塔上p-单位的泛模来描述F的所有Z_p-扩张的第一层的Kummer根A_F .我们还研究了与AF相关的“扭曲”自由基。

英文摘要:

For an odd prime p and a number field F containing a primitive p-th root of unity, we describe the Kummer radical A_F of the first layers of all the Z_p-extensions of F in terms of universal norms of p-units along the cyclotomic tower of F . We also study "twisted" radicals related to AF .
