(Un)distorted diffeomorphisms in different regularities
Andrés Navas
We build the first examples of diffeomorphisms that are distorted in a group of diffeomorphisms yet undistorted in the corresponding group of diffeomorphisms, where $r…
Uniformly perfect finitely generated simple left orderable groups
James Hyde, Yash Lodha, Andrés Navas +1
We show that the finitely generated simple left orderable groups constructed by the first two authors in arXiv:1807.06478 are uniformly perfect - each element in the group ca…
The further chameleon groups of Richard Thompson and Graham Higman: Automorphisms via dynamics for the Higman groups
Collin Bleak, Peter Cameron, Yonah Maissel +2
We describe, through the use of Rubin's theorem, the automorphism groups of the Higman-Thompson groups as groups of specific homeomorphisms of Cantor spaces $\mathfrak{C}…
Groups, orders, and laws
Andrés Navas
We discuss the question whether left-orderable groups satisfying a nontrivial law are locally indicable.
Sharp regularity for certain nilpotent group actions on the interval
G. Castro, E. Jorquera, A. Navas
According to the classical Plante-Thurston Theorem, all nilpotent groups of -diffeomorphisms of the closed interval are Abelian. Using techniques coming from the works of Denj…
A remarkable family of left ordered groups: central extensions of Hecke groups
Andrés Navas
We provide an infinite family of left-ordered groups, all of which have a positive cone that is finitely generated as a semigroup. This family includes the Klein bottle group and t…
