The $R_{\infty }$ property for nilpotent quotients of generalized solvable Baumslag-Solitar groups

Wagner C. Sgobbi, Dalton C. Silva, Daniel Vendrúscolo

We say a group $G$ has property $R_{\infty }$ if the number $R(\phi )$ of twisted conjugacy classes is infinite for every automorphism $\phi$ of $G$. For such groups, the $R_{\infty }$-nilpoten…
