Strongly Quasiconvex subgroups in graphs of groups

Hoang Thanh Nguyen, Hung Cong Tran

Given a graph of groups $G = (Γ, {G_{v}}, {G_{e}})$ with certain conditions on vertex groups and $G$ acts acylindrically on its Bass-Serre tree $T$ . Let $H$ be a finitely…

Divergence of finitely presented groups

Noel Brady, Hung Cong Tran

We construct families of finitely presented groups exhibiting new divergence behavior; we obtain divergence functions of the form $r^{α}$ for a dense set of exponents $α\in [2,\infty…

Quasiconvexity in $3$ -manifold groups

Hoang Thanh Nguyen, Hung Cong Tran, Wenyuan Yang

In this paper, we study strongly quasiconvex subgroups in a finitely generated $3$ --manifold group $π_{1} (M)$ . We prove that if $M$ is a compact, orientable $3$ --manifold that does n…
