对于一个素数和与1模相等的有限素数集,在有理数域的扩展上,我们考虑了最大的亲-对-可拓的外未分枝的伽罗瓦群。本文给出了一类伽罗瓦群为亚环亲群的s族,并应用了格林伯格猜想。
For a prime numberpand a finite setSof prime numbers congruent to 1 modulop, we consider the Galois group of the maximal pro-p-extension unramified outsideSover the-extension of the rational number field. In this paper, we give a family ofSfor which the Galois group is a metacyclic pro-pgroup with an application to Greenberg’s conjecture.
