A finitely presented infinite simple group of homeomorphisms of the circle

Yash Lodha

We construct a finitely presented, infinite, simple group that acts by homeomorphisms on the circle, but does not admit a non-trivial action by $C^{1}$ -diffeomorphisms on the circle.…

Hyperbolicity as an obstruction to smoothability for one-dimensional actions

Christian Bonatti, Yash Lodha, Michele Triestino

Ghys and Sergiescu proved in the $80$ s that Thompson's group $T$ , and hence $F$ , admits actions by $C^{\infty}$ diffeomorphisms of the circle . They proved that the standard action…

Two-chains and square roots of Thompson's group $F$

Thomas Koberda, Yash Lodha

We study two--generated subgroups $⟨ f, g ⟩ < Homeo^{+} (I)$ such that $⟨ f^{2}, g^{2} ⟩$ is isomorphic to Thompson's group $F$ , and such that the supports of $…
