Cb-frames for operator spaces
Rui Liu, Zhong-Jin Ruan
In this paper, we introduce the concept of cb-frames for operator spaces. We show that there is a concrete cb-frame for the reduced free group C*-algebra , which is der…
On exotic group C*-algebras
Zhong-Jin Ruan, Matthew Wiersma
Let be a discrete group. A -algebra is an exotic -algebra (associated to ) if there exist proper surjective -quotients . In this…
Realization of quantum group Poisson boundaries as crossed products
Mehrdad Kalantar, Matthias Neufang, Zhong-Jin Ruan
For a locally compact quantum group , consider the convolution action of a quantum probability measure on . As shown by Junge--Neufang--Ruan,…
-Representations of Discrete Quantum Groups
Michael Brannan, Zhong-Jin Ruan
Given a locally compact quantum group , we define and study representations and C-completions of the convolution algebra associated with various…
Exotic group C*-algebras
Matthew Wiersma
Let be a discrete group. When is nonamenable, the reduced and full group *-algebras differ and it is generally believed that there should be many intermediate *-algeb…
Poisson boundaries over locally compact quantum groups
Mehrdad Kalantar, Matthias Neufang, Zhong-Jin Ruan
We present versions of several classical results on harmonic functions and Poisson boundaries in the setting of locally compact quantum groups. In particular, the Choquet--Deny the…
