The fixed subgroups of homeomorphisms of Seifert manifolds

Qiang Zhang

Let $M$ be a compact connected orientable Seifert manifold with hyperbolic orbifold $B_{M}$ , and $f_{π} : π_{1} (M) \to π_{1} (M)$ be an automorphism induced by an orientation-reversing…

Fixed subgroups are compressed in surface groups

Qiang Zhang, Enric Ventura, Jianchun Wu

For a compact surface $Σ$ (orientable or not, and with boundary or not) we show that the fixed subgroup, $Fix B$ , of any family $B$ of endomorphisms of $π_{1} (Σ)$ is c…
