Groups of piecewise linear homeomorphisms of flows
Nicolás Matte Bon, Michele Triestino
To every dynamical system over a totally disconnected compact space, we associate a left-orderable group . It is defined as a group of homeomorphisms of the suspensio…

Property FW, differentiable structures, and smoothability of singular actions
Yash Lodha, Nicolás Matte Bon, Michele Triestino
We provide a smoothening criterion for group actions on manifolds by singular diffeomorphisms. We prove that if a countable group has the fixed point property FW for walls (e.g…
