On the distribution of class groups of number fields
arXiv:0912.1427 · doi:10.1063/1.3507135
Abstract
We propose a modification of the predictions of the Cohen--Lenstra heuristic for class groups of number fields in the case where roots of unity are present in the base field. As evidence for this modified formula we provide a large set of computational data which show close agreement.
