We introduce the notion of a space with measured walls, generalizing the concept of a space with walls due to Haglund and Paulin (Simplicite de groupes d'automorphismes d'espaces a courbure negative. Geom. Topol. Monograph1 (1998), 181–248). We obs

We provide a new approach to filter products of C0-semigroups and prove a spectral theorem for the generator and its filter product. In a similar fashion, we construct ultraproducts of strongly continuous unitary representations of locally compact gr

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

A telephone network can be modeled by a kind of graph called a uniform connector. In this model the notion of (n,k,d)-expander is defined to quantify the ability of a graph to transmit information; d is called the expanding constant. Let Г be a fini

We prove that in a certain statistical sense the Cayley graph of almost every finitely presented group with $m\ge 2$ generators contains a subdivision of the complete graph on $l\le 2m+1$ vertices. In particular, this Cayley graph is non planar. We a

The aim of this chapter is to establish the following classification result for connected Lie groups with the Haagerup property, already mentioned in Section1.4.
