Greenberg's conjecture and cyclotomic towers

Number Theory 2007-05-23 v1

Abstract

We describe Greenberg's pseudo-null conjecture, and prove a result describing conditions under which the pseudo-null conjecture for a number field KK implies the conjecture for finite extensions of KK. We then apply the result to the cyclotomic Zp\mathbb{Z}_p-tower above a cyclotomic field of prime roots of unity, verifying the conjecture for a large class of cyclotomic fields.
