Ping-pong dynamics of hyperbolic-like actions with non-simple points

KyeongRo Kim, Michele Triestino

A hyperbolic-like group is a subgroup of such that every non-trivial element has exactly two fixed points, one attracting and one repelling. We invest…

Locally moving groups and laminar actions on the line

Joaquín Brum, Nicolás Matte Bon, Cristóbal Rivas +1

We prove various results that, given a sufficiently rich subgroup of the group of homeomorphisms on the real line, describe the structure of the other possible actions of o…

Subexponential growth and actions on one-manifolds

Sang-hyun Kim, Nicolás Matte Bon, Mikael de la Salle +1

Let be a countable group with no finitely generated subgroup of exponential growth. We show that every action of on a countable set preserving a linear (respectively, circu…

Solvable Groups and Affine Actions on the Line

Joaquín Brum, Nicolás Matte Bon, Cristóbal Rivas +1

We prove a structural result for orientation-preserving actions of finitely generated solvable groups on real intervals, considered up to semi-conjugacy. As applications we obtain…

A realisation result for moduli spaces of group actions on the line

Joaquín Brum, Nicolás Matte Bon, Cristóbal Rivas +1

Given a finitely generated group , the possible actions of on the real line (without global fixed points), considered up to semi-conjugacy, can be encoded by the space of or…

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

Christian Bonatti, João Carnevale, Michele Triestino

A subgroup of is Möbius-like if every element is conjugate to an element of . In general, a Möbius-like subgroup of $…
