The unit norm index and $p$-class group in certain degree $\ell$ extensions

Number Theory 2020-11-04 v1

Abstract

We examine when units in a field are the norms of elements in an extension field, given certain conditions. We apply these results to the study of the \ell-class groups in lifts of the anti-cyclotomic Z2\mathbb{Z}_2-extension of Q(i)\mathbb{Q}(i).
