Leopoldt's Conjecture for CM fields
Abstract
The conjecture of Leopoldt states that the - adic regulator of a number field does not vanish. It was proved for the abelian case in 1967 by Brumer, using Baker theory. We prove this conjecture for CM number fields . The proof uses Iwasawa's methods -- especially Takagi Theory -- for deriving his skew symmetric pairing, together with Kummer- and Class Field Theory.

This is the final submitted version. I removed several results which were not actively used in the proof and massively streamlined and simplified the presentation. The proof is based on the vanishing of mu, which is proved in a separate paper. But there is an appendix which explains how the proof can be completed without assuming that proof, thus also if mu > 0 is assumed possible
