Infinite free pro-p products as absolute Galois groups

Tamar Bar-On

In this paper we prove a generalized version of Mel'nikov's Criterion, which has also been proved by Haran, and use it in order to connect the realization as absolute Galois groups…

Cofinality of Galois Cohomology within Purely Quadratic Graded Algebras

Tamar Bar-On, Ido Efrat

Let $p$ be a prime number. For a field $F$ containing a root of unity of order $p$ , let $H^{∙} (F) = H^{∙} (F, F_{p})$ be the mod- $p$ Galois cohomology graded $\mathbb{F}…

Free product of Demushkin groups as absolute Galois group

Tamar Bar-On

We prove that a free profinite (pro- $p$ ) product over a set converging to 1 of countably many Demushkin groups of rank $ℵ_{0}$ , $G_{i}$ , that can be realized as absolute Galois gr…

Demushkin groups of uncountable rank

Tamar Bar-On, Nikolay Nikolov

We extend the theory of countably generated Demushkin groups to Demushkin groups of arbitrary rank. We investigate their algebraic properties and invariants, count their isomorphis…
