Groups with rapid decay and trivial amenable radical are C*-simple
Caleb Barnett, Joseph Gondek, Mehrdad Kalantar
We prove that every finitely generated group with rapid decay and trivial amenable radical is C*-simple.
Invariant random subgroups of -simple groups
Tattwamasi Amrutam, Mehrdad Kalantar
Let be a countable discrete -simple group. Let be a -invariant Borel probability measure on , i.e., an IRS. We show that -almost every subgroup $H…
Stabilizer Subgroups and the Simplicity of Reduced Crossed Products
Yair Hartman, Mehrdad Kalantar
Given a minimal action of a countable group on a compact space , we prove that if the reduced crossed product is simple, then there ex…
Conjugacy co-amenability
Mehrdad Kalantar, Srivatsav Kunnawalkam Elayavalli
In this note we study a natural analytic property of inclusions of groups akin to co-amenability: the property of existence of a non-compactly supported invariant state for the con…
Growth conditions for topological freeness
Nazmul Alam, Joseph Gondek, Mehrdad Kalantar +1
Given a finitely generated group , a non-trivial element , and a minimal action on a compact space , with amenable neighborh…
Retraction Theorems for Group Compactifications
Yair Hartman, Aranka Hrušková, Mehrdad Kalantar +1
We characterize group compactifications of discrete groups for which there exists an equivariant retraction onto the boundary. In particular, we prove an equivariant analogue of Br…
