Two families of pro-p groups that are not absolute Galois groups
Claudio Quadrelli
Let be a prime. We produce two new families of pro- groups which are not realizable as absolute Galois groups of fields. To prove this we use the 1-smoothness property of ab…

Koszul algebras and quadratic duals in Galois cohomology
Jan Minac, Federico W. Pasini, Claudio Quadrelli +1
We investigate the Galois cohomology of finitely generated maximal pro- quotients of absolute Galois groups. Assuming the well-known conjectural description of these groups, we…
