Let K be a finitely generated field with separable closure K s and absolute Galois group G K. By a curve C/K we always understand a smooth geometrically irreducible projective curve. Let F (C) be its function field and let Π(C) be the Galois group of the maximal unramified extension of F (C). We have the exact sequence where Π g (C) is the geometric(More)
