Amalgamated Free Products of Circle Actions with a Bounded Number of Fixed Points

João Carnevale

Inspired by constructions of Kovačević, we introduce the amalgamated free product of circle actions, obtained by blowing up two actions along prescribed orbits and rearranging the…

Non-locally discrete actions on the circle with at most $N$ fixed points

Christian Bonatti, João Carnevale, Michele Triestino

A subgroup of $Homeo_{+} (S^{1})$ is Möbius-like if every element is conjugate to an element of $PSL (2, R)$ . In general, a Möbius-like subgroup of $\m…

Groups acting on the line with at most $2$ fixed points: an extension of Solodov's theorem

João Carnevale

A classical result by Solodov states that if a group acts on the line such that any non-trivial element has at most one fixed point, then the action is either abelian or semi-conju…
