### On the relation between 2 and infty in Galois cohomology of number fields, by Alexander Schmidt

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).
