$R_{\infty }$-property for groups commensurable to nilpotent quotients of RAAGs

Maarten Lathouwers, Thomas Witdouck

Let $G$ be a group and $\phi$ an automorphism of $G$. Two elements $x,y\in G$ are said to be $\phi$-conjugate if there exists a third element $z\in G$ such that $zx\phi (z{)}^{-1}=y$. Be…
