Limit groups with respect to Thompson's group $F$ and other hereditarily separating groups

Aleksander Ivanov, Roland Zarzycki

We prove that a limit group over Thompson's group $F$ cannot be an HNN-extension of $F$ with respect to a finitely generated subgroup. On the other hand we give an example of an $F…

Mixed identities, hereditarily separated actions and oscillation

Aleksander Ivanov, Roland Zarzycki

Given a topological $G$ -space we consider equations with parameters over $G$ . In particular we formulate some very general conditions on words with parameters $w (y ˉ, g ˉ)$ …
