Furstenberg Maps For CAT(0) Targets Of Finite Telescopic Dimension
arXiv:1404.3187 · doi:10.1017/etds.2014.147
Abstract
We consider actions of locally compact groups $G$ on certain CAT(0) spaces $X$ by isometries. The CAT(0) spaces we consider have finite dimension at large scale. In case $B$ is a $G$-boundary, that is a measurable $G$-space with amenability and ergodicity properties, we prove the existence of equivariant maps from $B$ to the visual boundary $\partial X$.
