Sur le sous-groupe des éléments de hauteur infinie du K2 d'un corps de nombres
arXiv:0801.0916
Abstract
By using the logarithmic approach of the classical kernels for the K2 of number fields, we compute the 2-rank of the wild kernel WK2(F) and the 2-rank of the subgroup of infinite heigh elements in K2(F) in terms of positive class groups for any number field F.
