Uniform embeddability (in a Hilbert space), introduced by Gromov, is a geometric property of metric spaces. As applied to countable discrete groups, it has important consequences for the Novikov conjecture. Exactness, introduced and studied extensively by Kirchberg and Wassermann, is a functional analytic property of locally compact groups. Recently it has become apparent that, as properties of countable discrete groups, uniform embeddability and exactness are closely related. We further… 
Uniform Embeddability into Hilbert Space
The open question of what prevents a metric space with bounded geometry from being uniformly embeddable in Hilbert space is answered here for box spaces of residually finite groups. We prove that a
Discrete groups with finite decomposition complexity
In [GTY] we introduced a geometric invariant, called finite decomposition complexity (FDC), to study topological rigidity of manifolds. In that article we proved the stable Borel conjecture for a
Coarse embeddings of metric spaces into Banach spaces
There are several characterizations of coarse embeddability of locally finite metric spaces into a Hilbert space. In this note we give such characterizations for general metric spaces. By applying
Strong embeddability and extensions of groups
We introduce the notion of strong embeddability for a metric space. This property lies between coarse embeddability and property A. A relative version of strong embeddability is developed in terms of
A quasi-isometric embedding theorem for groups
We show that every group $H$ of at most exponential growth with respect to some left invariant metric admits a bi-Lipschitz embedding into a finitely generated group $G$ such that $G$ is amenable

On coarse embeddability into $ℓ_p$-spaces and a conjecture of Dranishnikov
We show that the Hilbert space is coarsely embeddable into any lp for 1 � p � 1. It follows that coarse embeddability into l2 and into lp are equivalent for 1 � p 2 due to a recent result of W.
A notion of geometric complexity and its application to topological rigidity
We introduce a geometric invariant, called finite decomposition complexity (FDC), to study topological rigidity of manifolds. We prove for instance that if the fundamental group of a compact
The coarse Novikov conjecture for extensions of coarsely embeddable groups
Let (1 → Nn → Gn → Qn → 1)n∈N be a sequence of extensions of countable discrete groups. Endow (Gn)n∈N with metrics associated to proper length functions on (Gn)n∈N respectively such that the sequence


The coarse Baum–Connes conjecture for spaces which admit a uniform embedding into Hilbert space
Corollary 1.2. Let Γ be a finitely generated group. If Γ, as a metric space with a word-length metric, admits a uniform embedding into Hilbert space, and its classifying space BΓ has the homotopy
The coarse Baum – Connes conjecture and groupoids
To every discrete metric space with bounded geometry X we associate a groupoid G(X ) for which the coarse assembly map for X is equivalent to the Baum–Connes assembly map for G(X ) with coe2cients in
Uniform Embeddings into Hilbert Space and a Question of Gromov
Abstract Gromov introduced the concept of uniform embedding into Hilbert space and asked if every separable metric space admits a uniform embedding into Hilbert space. In this paper, we study uniform
Novikov Conjectures, Index Theorems and Rigidity
This is an expository paper explaining coarse analogues of the Novikov Conjecture and describing how information on the original Novikov Conjecture can be derived from these. For instance, we will

Free Products of Exact Groups
It has recently been proved that the class of unital exact C*-algebras is closed under taking reduced amalgamated free products. Here the proof is presented of a special case: that the class of exact

Exactness of reduced amalgamated free product C*-algebras
Some completely positive maps on reduced amalgamated free products of C*-algebras are constructed; these allow a proof that the class of exact unital C*-algebras is closed under taking reduced
