Let K/k be a finite Galois extension of number fields with Galois group G, and let S be a finite G-stable set of primes of K containing all archimedean primes. We denote the G-module of S-units of K by E = ES and let ∆S be the kernel of the augmentation map ZS → Z which sends each basis element p ∈ S to 1. We are concerned with invariants of K/k which are(More)

The interest in doing so comes from recent work in Iwasawa theory in which refined ‘main conjectures’ are formulated in terms of the K-theory of completed group algebras Zl[[G]] with G an l-adic Lie group (see [FK], [RW2]). For l-adic Lie groups of dimension 1, use of the integral logarithm L has reduced the ‘main conjecture’ to questions of the existence(More)
