Abstract: We remove the assumption "let p be
odd or k totally imaginary"
from several well-known theorems in Galois cohomology of
number fields. For example, we show that the Galois group
of the
maximal extension of a number field k which is unramified
outside 2
has a finite cohomological 2-dimension (also if k has real
places). |
