Growth rate of endomorphisms of Houghton's groups
Jong Bum Lee, Sang Rae Lee
A Houghton's group consists of translations at infinity of a rays of discrete points on the plane. In this paper we study the growth rate of endomorphisms of Ho…
The property for Houghton's groups
Jang Hyun Jo, Jong Bum Lee, Sang Rae Lee
We study twisted conjugacy classes of a family of groups which are called Houghton's groups (), the group of translations of rays of discrete p…
Geometry of Houghton's Groups
Sang Rae Lee
Hougthon's groups H_n is a family of groups where each H_n consists of `translations at infinity' on n rays of discrete points emanating from the origin on the plane. Brown shows H…
Dehn functions and finiteness properties of subgroups of perturbed right-angled Artin groups
Noel Brady, Dan Guralnik, Sang Rae Lee
We introduce the class of perturbed right-angled Artin groups. These are constructed by gluing Bieri double groups into standard right-angled Artin groups. As a first application o…
