Dynamical propagation and Roe algebras of warped spaces
Tim de Laat, Federico Vigolo, Jeroen Winkel
Given a non-singular action , we define the -algebra of operators of finite dynamical propagation associated w…
Exotic group -algebras of simple Lie groups with real rank one
Tim de Laat, Timo Siebenand
Exotic group -algebras are -algebras that lie between the universal and the reduced group -algebra of a locally compact group. We consider simple Lie groups with…
The Fourier algebra of a rigid -tensor category
Yuki Arano, Tim de Laat, Jonas Wahl
Completely positive and completely bounded mutlipliers on rigid -tensor categories were introduced by Popa and Vaes. Using these notions, we define and study the Fourier-…
Howe-Moore type theorems for quantum groups and rigid C*-tensor categories
Yuki Arano, Tim de Laat, Jonas Wahl
We formulate and study Howe-Moore type properties in the setting of quantum groups and in the setting of rigid -tensor categories. We say that a rigid -tensor c…
Approximation properties for noncommutative -spaces of high rank lattices and nonembeddability of expanders
Tim de Laat, Mikael de la Salle
This article contains two rigidity type results for for large that share the same proof. Firstly, we prove that for every differe…
Simple Lie groups without the Approximation Property II
Uffe Haagerup, Tim de Laat
We prove that the universal covering group of does not have the Approximation Property (AP). Together with the f…
On the Grothendieck Theorem for jointly completely bounded bilinear forms
Tim de Laat
We show how the proof of the Grothendieck Theorem for jointly completely bounded bilinear forms on C*-algebras by Haagerup and Musat can be modified in such a way that the method o…
Approximation properties for noncommutative Lp-spaces associated with lattices in Lie groups
Tim de Laat
In 2010, Lafforgue and de la Salle gave examples of noncommutative Lp-spaces without the operator space approximation property (OAP) and, hence, without the completely bounded appr…
Simple Lie groups without the Approximation Property
Uffe Haagerup, Tim de Laat
For a locally compact group G, let A(G) denote its Fourier algebra, and let M_0A(G) denote the space of completely bounded Fourier multipliers on G. The group G is said to have the…
