The $R_{\infty}$ 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 $H_{n}$ ( $n \in N$ ), the group of translations of $n$ rays of discrete p…

Growth rate for endomorphisms of finitely generated nilpotent groups and solvable groups

Alexander Fel'shtyn, Jang Hyun Jo, Jong Bum Lee

We prove that the growth rate of an endomorphism of a finitely generated nilpotent group equals to the growth rate of induced endomorphism on its abelinization, generalizing the co…
