PROPER AFFINE ACTIONS FOR RIGHT-ANGLED COXETER GROUPS

It is known (see [CCJ + 01], Corollary 7.4.2) that, if G belongs to the class PW, then G has the Haagerup property (or is a-T-menable), i.e.. Up to now, the problem of stability of

We show that a group acting on a non-trivial tree with finite edge stabilizers and icc vertex stabilizers admits a faithful and highly transitive action on an infinite countable

Thus, as an immediate consequence of Theorem 2.4.2, we have that a fundamental group of a graph of groups whose vertex groups are all finite p-groups is conjugacy p-separable if

The numbers of conjugacy classes of finite subgroups determine the 3- conjugacy classes graph and hence the quotient of the reduced 3–torsion sub-complex for all finite index

In the rest of this subsection we give an example of a hyperbolic domain of holo- morphy in a 3–dimensional Stein solvmanifold endowed with a proper R –action such that the Z

It is known (see [CCJ + 01], Corollary 7.4.2) that, if G belongs to the class PW, then G has the Haagerup property (or is a-T-menable), i.e. Up to now, the problem of stability of

Assume that Z is a holomorphic vector field with an isolated, non–nilpotent singularity at (0,0). In general it is not possible to give simpler models. The second result addresses
