SAT actions of discrete quantum groups and minimal injective extensions of their von Neumann algebras
Mehrdad Kalantar, Fatemeh Khosravi, Mohammad S. M. Moakhar
We introduce a natural generalization of the notion of strongly approximately transitive (SAT) states for actions of locally compact quantum groups. In the case of discrete quantum…
A type I conjecture and boundary representations of hyperbolic groups
Pierre-Emmanuel Caprace, Mehrdad Kalantar, Nicolas Monod
We establish new results on the weak containment of quasi-regular and Koopman representations of a second countable locally compact group associated with non-singular -space…
Tight inclusions of C*-dynamical systems
Yair Hartman, Mehrdad Kalantar
We study a notion of tight inclusions of C*- and W*-dynamical systems which is meant to capture a tension between topological and measurable rigidity of boundary actions. An import…
On invariant subalgebras of group and von Neumann algebras
Mehrdad Kalantar, Nikolaos Panagopoulos
Given an irreducible lattice in the product of higher rank simple Lie groups, we prove a co-finiteness result for the -invariant von Neumann subalgebras of the group von Neu…
Boundary maps and covariant representations
Mehrdad Kalantar, Eduardo Scarparo
We extend applications of Furstenberg boundary theory to the study of -algebras associated to minimal actions of discrete groups on locally compa…
