A Class Number Problem for the Cyclotomic Z2-extension of Q(√5)

Research output: Contribution to journalArticle

Abstract

Let Kn be the n-th layer of the cyclotomic Z2-extension of Q( √ 5) and hn the class number of Kn. We prove that, if ℓ is a prime number less than 6 104, then ℓ does not divide hn for any non-negative integer n.
