Residual Finiteness Growth in Virtually Nilpotent Groups

Jonas DerÃ©, Joren Matthys, Lukas Vandeputte

The residual finiteness growth $RF_{G} : N \to N$ of a finitely generated group $G$ is a function that gives the smallest value of the index $[G : N]$ with $N$ …

Residual Finiteness Growth in Minimax Groups

Jonas DerÃ©, Joren Matthys

If $g \in G$ is a non-trivial element in a residually finite group, then there exists by definition a finite group $Q$ and a homomorphism $I ¨ : G \to Q$ such that $I ¨ (g) \neq = e$ . The…

Residual Finiteness Growth in Two-Step Nilpotent Groups

Given a finitely generated residually finite group $G$ , the residual finiteness growth $RF_{G} : N \to N$ bounds the size of a finite group $Q$ needed to dete…
