Starting with seminal work by Masur-Minsky, a lot of machinery has been
developed to study the geometry of Mapping Class Groups, and this has
lead, for example, to the proof of quasi-isometric rigidity results.
Parts of this machinery include hyperbolicity of the curve complex, the
distance formula and hierarchy paths.
As it turns out, all this can be transposed to the context of CAT(0)
cube complexes. I will explain some of the key parts of the machinery
and then I will discuss results about quasi-Lipschitz maps from
Euclidean spaces and nilpotent Lie groups into "spaces with a distance
formula".
Joint with Jason Behrstock and Mark Hagen.
