We study the ideal structure of reduced crossed product of topological dynamical systems of a countable discrete group. More concretely, for a compact Hausdorff space $X$ with an action of a countable discrete group $\Gamma$, we consider the absence of a non-zero ideals in the reduced crossed product $C(X) \rtimes_r \Gamma$ which has a zero intersection with $C(X)$. We characterize this condition by a property for amenable subgroups of the stabilizer subgroups of $X$ in terms of the Chabauty… 
Furstenberg Boundary of Minimal Actions
For a countable discrete group $$\Gamma $$ Γ and a minimal $$\Gamma $$ Γ -space X , we study the notion of $$(\Gamma , X)$$ ( Γ , X ) -boundary, which is a natural generalization of the notion of
A generalized powers averaging property for commutative crossed products
We prove a generalized version of Powers’ averaging property that characterizes simplicity of reduced crossed products C(X) ⋊λ G, where G is a countable discrete group, and X is a compact Hausdorff
Noncommutative boundaries and the ideal structure of reduced crossed products
A C*-dynamical system is said to have the ideal separation property if every ideal in the corresponding crossed product arises from an invariant ideal in the C*-algebra. In this paper we characterize
On minimal actions of countable groups
Our purpose here is to review some recent developments in the theory of dynamical systems whose common theme is a link between minimal dynamical systems, certain Ramsey type combinatorial properties,
A type I conjecture and boundary representations of hyperbolic groups
. We establish new results on the weak containment of quasi-regular and Koopman representations of a second countable locally compact group G associated with non-singular G -spaces. We deduce that

A connection between boundary actions, ideal structure of reduced crossed products and C*-simple group is imminent.We investigate the stability properties for discrete group pioneered by powers and
The ideal intersection property for essential groupoid C*-algebras
We characterise, in several complementary ways, étale groupoids with locally compact Hausdorff space of units whose essential groupoid C∗-algebra has the ideal intersection property, assuming that
Injective envelopes and the intersection property
We consider the center of Hamana's equivariant injective envelope of a unital $C^*$-algebra equipped with an action of a discrete group. We show that the center of the equivariant injective envelope

Uniformly recurrent subgroups
We define the notion of uniformly recurrent subgroup, URS in short, which is a topological analog of the notion of invariant random subgroup (IRS), introduced in a work of M. Abert, Y. Glasner and B.

C*-simplicity and the unique trace property for discrete groups
A discrete group is said to be C*-simple if its reduced C*-algebra is simple, and is said to have the unique trace property if its reduced C*-algebra has a unique tracial state. A dynamical
C*-simplicity and the amenable radical
A countable group is C*-simple if its reduced C*-algebra is simple. It is well known that C*-simplicity implies that the amenable radical of the group must be trivial. We show that the converse does

Characterizations of C*-simplicity
We characterize discrete groups that are C*-simple, meaning that their reduced C*-algebra is simple. First, we prove that a discrete group is C*-simple if and only if it has Powers' averaging
