On two-generator subgroups of mapping torus groups

Naomi Andrew, Edgar A. Bering, Ilya Kapovich +2

We prove that if $G_{ϕ} = ⟨ F, t ∣ t x t^{- 1} = ϕ (x), x \in F ⟩$ is the mapping torus group of an injective endomorphism $ϕ : F \to F$ of a free group $F$ (of possibly infinite r…

Finiteness properties of algebraic fibers of group extensions

Dessislava H. Kochloukova, Stefano Vidussi

This survey describes some recent work, by the authors and others, on the existence of algebraic fibrations of group extensions, as well as the finiteness properties of their algeb…

Higher incoherence of the automorphism groups of a free group

Stefano Vidussi

Let $F_{n}$ be the free group on $n \geq 2$ generators. We show that for all $1 \leq m \leq 2 n - 3$ (respectively for all $1 \leq m \leq 2 n - 4$ ) there exists a subgroup of $\operatornam…

Higher dimensional algebraic fiberings of group extensions

Dessislava H. Kochloukova, Stefano Vidussi

We prove some conditions for the existence of higher dimensional algebraic fibering of group extensions. This leads to various corollaries on incoherence of groups and some geometr…

Incoherence of free-by-free and surface-by-free groups

Robert Kropholler, Stefano Vidussi, Genevieve Walsh

Let $G$ be the semidirect product $Γ ⋊ F_{2}$ where $Γ$ is either the free group $F_{n}$ , $n > 1$ or the fundamental group $S_{g}$ of a closed surface of genus $g > 1$ . We prove tha…
