= Limit set of an infinite normal Kleinian subgroup
{title2=$N\mathrel{\triangleleft}\Gamma,\quad |N|=\infty\implies\Lambda(N)=\Lambda(\Gamma)$}
The <Kleinian limit set> of an infinite subgroup is nonempty. If it is normal, its limit set is invariant under the ambient group by base-point independence and conjugation. <Minimality of the Kleinian limit set> gives one inclusion, and subgroup containment gives the other. Neither properness nor finite generation of the subgroup is needed.
