Fixed subgroups in direct products of surface groups of Euclidean type
Jianchun Wu, Enric Ventura, Qiang Zhang
We give an explicit characterization of which direct products of surface groups of Euclidean type satisfy that the fixed subgroup of any automorphism (or endomorphism) of i…

Fixed subgroups are compressed in surface groups
Qiang Zhang, Enric Ventura, Jianchun Wu
For a compact surface (orientable or not, and with boundary or not) we show that the fixed subgroup, , of any family of endomorphisms of is c…

The group fixed by a family of endomorphisms of a surface group
Jianchun Wu, Qiang Zhang
For a closed surface with , we show that the fixed subgroup of a family of endomorphisms of has $\rk \fix\mathcal B\leq \rk π_1(S)$. In particular…
