We show that group actions on many treelike compact spaces are not too complicated
dynamically. We first observe that an old argument of Seidler (1990) implies that every …

We study the bounded cohomology of certain groups acting on the Cantor set. More
specifically, we consider the full group of homeomorphisms of the Cantor set as well as …

Let $ G $ be the homeomorphism group of a dendrite. We study the normal subgroups of $ G
$. For instance, there are uncountably many non-isomorphic such groups $ G $ that are …

It is shown that the restriction of the action of any group with finite orbit on the minimal sets of
local dendrites is equicontinuous. Consequently, we obtain that the action of any amenable …

Kaleidoscopic groups are a class of permutation groups recently introduced by Duchesne,
Monod, and Wesolek. Starting with a permutation group Γ, the kaleidoscopic construction …

Homeomorphism groups of generalized Ważewski dendrites act on the infinite countable set
of branch points of the dendrite and thus have a nice Polish topology. In this paper, we study …

We exhibit a topological group with property (T) acting nonelementarily and continuously on
the circle. This group is an uncountable totally disconnected closed subgroup of. It has a …

A continuous action of a topological group G on a compact topological space X is called a
flow (G, X). Particular attention was paid to the study of groups acting on dendrites [14, 10 …

Glasner and Megrelishvili proved that every continuous action of a topological group $ G $
on a dendrite $ X $ is tame. We produce two examples of an action on a dendrite which is …
