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…
Random walks on dense subgroups of locally compact groups
Michael Björklund, Yair Hartman, Hanna Oppelmayer
Let be a countable discrete group, a lcsc totally disconnected group and a homomorphism with dense image. We develop a general and explicit technique wh…
Kudo-Continuity Of Entropy Functionals
Michael Björklund, Yair Hartman, Hanna Oppelmayer
We study in this paper real-valued functions on the space of all sub--algebras of a probability measure space, and introduce the notion of Kudo-continuity, which is an a priori…
The stabilized automorphism group of a subshift
Yair Hartman, Bryna Kra, Scott Schmieding
For a mixing shift of finite type, the associated automorphism group has a rich algebraic structure, and yet we have few criteria to distinguish when two such groups are isomorphic…
Choquet-Deny groups and the infinite conjugacy class property
Joshua Frisch, Yair Hartman, Omer Tamuz +1
A countable discrete group is called Choquet-Deny if for every non-degenerate probability measure on it holds that all bounded -harmonic functions are constant. We s…
