Fixed-point property for affine actions on a Hilbert space

Group Theory 2017-05-09 v1 Differential Geometry

Abstract

Gromov showed that for fixed, arbitrarily large C, any uniformly C-Lipschitz affine action of a random group in his graph model on a Hilbert space has a fixed point. We announce a theorem stating that more general affine actions of the same random group on a Hilbert space have a fixed point. We discuss some aspects of the proof.
