Sur le sous-groupe des \'el\'ements de hauteur infinie du K2 d'un corps de nombres

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.
