Compact Invariant Random Subgroups
Tal Cohen, Helge Glöckner, Gil Goffer +1
We study ergodic invariant random subgroups that give full measure to the subset of compact subgroups. We show that in real Lie groups, compactly generated -adic Lie groups, loc…
Critical exponents of boomerang subgroups in the free group
Waltraud Lederle
We construct, for the free group acting on its Cayley tree, boomerang subgroups whose critical exponent is arbitrarily close to the critical exponent of a given finitely generated…
Elementwise conservative actions and new constructions of boomerang subgroups
Yair Glasner, Tobias Hartnick, Waltraud Lederle
We show that countable non-abelian free groups admit uncountably many mutually singular elementwise conservative non-singular random subgroups, which are supported on infinite subg…
Cayley-Abels graphs: Local and global perspectives
Waltraud Lederle
We give an introduction to the Cayley-Abels graph for a totally disconnected, locally compact (tdlc) group. It is a generalization of the Cayley graph. We illustrate that on the on…
Cayley--Abels graphs and invariants of totally disconnected, locally compact groups
Arnbjörg Soffía Árnadóttir, Waltraud Lederle, Rögnvaldur G. Möller
A connected, locally finite graph is a Cayley--Abels graph for a totally disconnected, locally compact group if acts vertex-transitively with compact, open vertex stabi…
Conjugacy and Dynamics in Almost Automorphism Groups of Trees
Gil Goffer, Waltraud Lederle
We determine when two almost automorphisms of a regular tree are conjugate. This is done by combining the classification of conjugacy classes in the automorphism group of a level-h…
