Abstract
The author proves that every Abelian subgroup of rank > 1 in the Galois group [Equation found] of the algebraic closure of a rational function field K is contained in a ramification subgroup and also that the unramified Brauer group BrvK equals the unramified Brauer group Brv(Gc) defined in [2] §3 where Gcis the quotient group Gc= G/[[G G] G].
