Topological behaviour of logarithmic invariants

Number Theory 2019-05-07 v1

Abstract

Let \ell be a rational prime number and KK a number field. We prove that the logarithmic module XdX_{d} attached to a Zd\mathbb{Z}_{\ell}^{d}-extension KdK_{d} of KK is a noetherian Λd\Lambda_{d}-module. Moreover, under the Gross-Kuz'min conjecture we prove that it is also torsion. We exploit this fact to deduce local and global information of the logarithmic invariants μ~\tilde{\mu} and λ~\tilde{\lambda} of Z\mathbb{Z}_{\ell}-extensions.
