The conjugacy problem in cyclic extensions of one-ended hyperbolic groups

Armando Martino

Let $G$ be a torsion-free one-ended hyperbolic group and let $ϕ \in Aut (G)$ . We prove that the mapping torus, or suspension, $M := G_{ϕ} = G ⋊_{ϕ} Z$ has sol…

Automorphism-invariant refinements of weakly branch actions via overlap functions

Armando Martino

Let a finitely generated group $G$ act weakly branch on a locally finite rooted tree $T$ with boundary $\partial T$ . The rooted tree structure is encoded by the \textit{overlap fun…
