Property FW and 1-dimensional piecewise groups
Yves Cornulier
Property FW is a natural combinatorial weakening of Kazhdan's Property T. We prove that the group of piecewise homographic self-transformations of the real projective line, has "fe…

Realizations of groups of piecewise continuous transformations of the circle
Yves Cornulier
We study the near action of the group PC of piecewise continuous self-transformations of the circle. Elements of this group are only defined modulo indeterminacy on a finite subset…

Commensurating actions for groups of piecewise continuous transformations
Yves Cornulier
We use partial actions, as formalized by Exel, to construct various commensurating actions. We use this in the context of groups piecewise preserving a geometric structure, and we…
