On the Cohomological Dimension of Some Pro-p-Extensions
This talk deals with pro-p-extensions of number fields and function fields with cohomological dimension at most 2. I will first recall some old results concerning Galois groups of type , then I will discuss the method introduced by Labute and Schmidt to control the case "S finite" and give some corollaries concerning Tsfasman-Vladuts
`s and I will conclude giving new situations for number fields with
(joint work with Blondeau and Maire).
