    HAAGERUP PROPERTY FOR SUBGROUPS OF SL2 AND RESIDUALLY FREE GROUPS YVES DE CORNULIER Abstract. In this note, we prove that all subgroups of SL(2,R) have the Haagerup property if R is a commutative reduced ring. This is based on the case case when R is a field, recently established by Guentner, Higson, and Weinberger. The Mathematical Sciences Research Institute (MSRI), founded in , is an independent nonprofit mathematical research institution whose funding sources include the National Science Foundation, foundations, corporations, and more than 90 universities and institutions. The Institute is located at 17 Gauss Way, on the University of California, Berkeley campus, close to Grizzly Peak, on the.

    Both papers with Yves Stalder and Alain Valette, classified here in "commensurating actions", deal with the Haagerup Property too.

This volume is the proceedings of the meeting, and collects survey and research articles in this fast-growing field by international specialists.

    The aim of this note is to prove that the group of Formanek-Procesi acts properly isometrically on a finite dimensional CAT(0) cube complex. This gives a first example of a non-linear semidirect product between two non abelian free groups which satisfies the Haagerup property. Theorem 1. Let H be a finite group. If G is a group in PW, then so is H wreathproduct G. In particular, H wreathproduct G has the Haagerup Property. This latter statement will be generalized in a forthcoming paper, where we prove that the Haagerup Property is closed under taking wreath by:

A locally compact group has the Haagerup property, or is a-T-menable in the sense of Gromov, if it admits a proper isometric action on some affine Hilbert space.

As Gromov's pun is trying to indicate, this definition is designed as a strong negation to Kazhdan's property (T), characterized by the fact that every isometric action on some affine Hilbert space has a fixed point.

A locally compact group has the Haagerup property, or is a-T-menable in the sense of Gromov, if it admits a proper isometric action on some affine Hilbert space. This book covers various aspects of the Haagerup property.

The aim of this chapter is to establish the following classification result for connected Lie groups with the Haagerup property, already mentioned in Section Keywords Relative Property Unitary Representation Spherical Function Closed Subgroup Positive Definite FunctionAuthor: Pierre-Alain Cherix, Michael Cowling, Alain Valette.

The class includes Thompson's groups, which have already been shown to have the Haagerup property by D. Farley, as well as many other groups acting on boundaries of trees.

Haagerup property, but examples are given of groups with the weak Haagerup property which are not weakly amenable and do not have the Haagerup property. In the second part of the paper we introduce the weak Haagerup property for finite von Neumann algebras, and we prove several hereditary results here as by: negative definite.

An extensive treatment of the Haagerup property for groups can be found in the book [CCJJV]. The Haagerup property is a strong negation to Kazhdan’s property T, in that each of the equivalent definitions above stands opposite to a definition of property T cf.

Haagerup property (or a-T-menability) for locally compact groups is generalised to the context of locally compact quantum groups, with several equivalent characterisations in terms of the unitary representations and positive-definite functions established.

For a time the only known source of non-PW (countable) groups was the class of groups without the Haagerup Property, and the only known source of groups without the Haagerup Property was groups Author: Yves de Cornulier.

Since the seminal paper of Haagerup [14], showing that free groups have the (now so-called) Haagerup property, or property (H), this notion plays an increasingly im-portant role in group theory (see the book [10]).

A similar property (H) has been introduced for finite von Neumann algebras [12, 11] and it was proved in [11] that a countable. A central idea in Haagerup’s proof is that the free group has a certain approximation property: the constant function 1 on F2 can be approximated pointwise by positive de nite functions vanishing at in nity.

This fact initiated the study of groups with what is now called the Haagerup property (De nition ). Listing only property by Estate Agents Council registered estate agents, you are assured that you are in safe hands when rent your property through one of 's registered estate agencies.

If you are looking to rent out your property in Zimbabwe, make sure you use one of listed agencies. For example, for the groups with the Haagerup property, the Baum–Connes conjecture is true, and consequently many important conjectures (e.g., the Novikov conjecture, the Kaplansky conjecture, etc.) are also true.

Moreover, the groups with the Haagerup property do not have (relative) property (T), which is a rigidity property of discrete by: INFINITELY PRESENTED SMALL CANCELLATION GROUPS HAVE THE HAAGERUP PROPERTY GOULNARA ARZHANTSEVA AND DAMIAN OSAJDA In memory of Kamil Duszenko prove the Haagerup property (= Gromov’s a-T-menability) for finitely generated groups defined by infinite presentations satisfying the C0(1=6)–small cancella- tion condition.

Clearly, the weak Haagerup property is weaker than both the Haagerup property and weak amenability, and hence there are many known examples of groups with the weak Haagerup property.

Moreover, there exist examples of groups that fail the first two properties but nevertheless have the weak Haagerup property (see [27, Corollary ]).Cited by: 3. The primary focus of this book is to cover the foundations of geometric group theory, including coarse topology, ultralimits and asymptotic cones, hyperbolic groups, isoperimetric inequalities, growth of groups, amenability, Kazhdan's Property (T) and the Haagerup property, as well as their characterizations in terms of group actions on median.Select Publications Select Publications.
