Abstract:We describe Greenberg's pseudo-null conjecture, and prove a result describing conditions under which the pseudo-null conjecture for a number field K implies the conjecture for finite extensions of K. We then apply the result to the cyclotomic Z p -tower above a cyclotomic field of prime roots of unity, verifying the conjecture for a large class of cyclotomic fields.
