The 2-Ideal Class Groups of ℚ(ζl)
Published online by Cambridge University Press: 22 January 2016
Abstract
For prime l we study the structure of the 2-part of the ideal class group Cl of ℚ(ζl). We prove that Cl ⊗ ℤ2) is a cyclic Galois module for all l < 10000 with one exception and compute the explicit structure in several cases.
