Pro- Poincaré-Duality groups of infinite rank

Tamar Bar-On

We introduce the class of \textit{Generalized Poincaré-Duality groups}: i.e, pro- groups of infinite rank which satisfy a Poincaré-duality. We prove some basic properties of Gen…

Groups of profinite type and profinite rigidity

Tamar Bar-On, Nikolay Nikolov

We say that a group is of \textit{profinite type} if it can be realized as a Galois group of some field extension. Using Krull's theory, this is equivalent to the ability of $G…

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…
