Non-closed subgroups of weakly branch groups
Jorge Fariña-Asategui, Paul-Henry Leemann, Tatiana Nagnibeda
For a weakly branch group acting on a regular enough rooted tree, we provide two constructions of continuous families of distinct subgroups that are not closed in the profinite…
Limits of Rauzy graphs of languages with subexponential complexity
Paul-Henry Leemann, Tatiana Nagnibeda, Alexandra Skripchenko +1
To a subshift over a finite alphabet, one can naturally associate an infinite family of finite graphs, called its Rauzy graphs. We show that for a subshift of subexponential comple…
On the structure of finitely generated subgroups of branch groups
Dominik Francoeur, Rostislav Grigorchuk, Paul-Henry Leemann +1
We describe the block structure of finitely generated subgroups of branch groups with the so-called subgroup induction property, including the first Grigorchuk group …
Cone Types and Spectral Radius of Hyperbolic Triangle Groups and Hyperbolic Tessellations
Megan Howarth, Tatiana Nagnibeda
This paper is devoted to the study of tessellations of the hyperbolic plane, especially the ones associated to hyperbolic triangle groups . We give a full description of…
The planar -colorable subgroup of Thompson's group and its even part
Valeriano Aiello, Tatiana Nagnibeda
We study the planar -colorable subgroup of Thompson's group and its even part . The latter is obtained by cutting with a…
