A class number calculation of the 5th layer of the cyclotomic z2-extension of q(5)

Research output: Contribution to journalArticlepeer-review

Abstract

For a positive integer n, let Kn be the n-th layer of the the cyclotomic Z2-extension of Q(5), which is the real quadratic field with the minimal discriminant. We prove that the class number of K5 is 1.
