The Congruence Subgroup Problem for finitely generated Nilpotent Groups

David El-Chai Ben-Ezra, Alexander Lubotzky

The congruence subgroup problem for a finitely generated group $Γ$ and $G \leq A u t (Γ)$ asks whether the map $G^\to A u t (Γ^)$ is injective, or more generally, what is its kern…

On Pro- $2$ Identities of $2 \times 2$ Linear Groups

David El-Chai Ben-Ezra, Efim Zelmanov

Let $F^$ be a free pro- $p$ non-abelian group, and let $Δ$ be a commutative Noetherian complete local ring with a maximal ideal $I$ such that $char (Δ/ I) = p > 0$ . In [Zu],…

The Congruence Subgroup Problem for the Free Metabelian group on $n \geq 4$ generators

David El-Chai Ben-Ezra

The congruence subgroup problem for a finitely generated group $Γ$ asks whether the map $A u t (Γ)^\to A u t (Γ^)$ is injective, or more generally, what is its kernel…

The Congruence Subgroup Problem for low rank Free and Free Metabelian groups

David El-Chai Ben-Ezra, Alexander Lubotzky

The congruence subgroup problem for a finitely generated group $Γ$ asks whether $A u t (Γ) \to A u t (Γ^)$ is injective, or more generally, what is its kernel $C\l…
