Divergence of finitely presented subgroups of CAT(0) groups
Noel Brady, Hung Cong Tran
We construct families of groups containing finitely presented groups whose divergence functions are of the form for a dense set of exponents and $r…

Coarse Alexander duality for pairs and applications
G. Christopher Hruska, Emily Stark, Hung Cong Tran
For a group (of type ) acting properly on a coarse Poincaré duality space , Kapovich-Kleiner introduced a coarse version of Alexander duality between and its compleme…

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 for a dense set of exponents $α\in [2,\infty…
