On distortion of normal subgroups
Hung Cong Tran
We examine distortion of finitely generated normal subgroups. We show a connection between subgroup distortion and group divergence. We suggest a method computing the distortion of…

Divergence spectra and Morse boundaries of relatively hyperbolic groups
Hung Cong Tran
We introduce a new quasi-isometry invariant, called the divergence spectrum, to study finitely generated groups. We compare the concept of divergence spectrum with the other classi…

Geometric embedding properties of Bestvina-Brady subgroups
Hung Cong Tran
We compute the relative divergence and the subgroup distortion of Bestvina-Brady subgroups. We also show that for each integer , there is a free subgroup of rank of so…
