The R∞ property for Houghton’s groups

초록

We study twisted conjugacy classes of a family of groups which are called Houghton’s groups H<inf>n</inf> (n ∈ ℕ), the group of translations of n rays of discrete points at infinity. We prove that the Houghton’s groups H<inf>n</inf> have the R∞ property for all n ∈ ℕ. © Journal “Algebra and Discrete Mathematics”.
