The group $PL_{+} (I)$ of increasing piecewise linear self-homeomorphisms of the interval $I = [0, 1]$ may not be assigned a topology in such a way that it becomes a Polish…

Some applications of Hölder's theorem in groups of analytic diffeomorphisms of 1-manifolds

Azer Akhmedov, Michael P. Cohen

We obtain a simple obstruction to embedding groups into the analytic diffeomorphism groups of 1-manifolds. Using this, we classify all RAAGs which embed into $\mathrm{Diff}_{+}^{ω}…
