Sub-riemannian geometry and beyond, III

Geometry and rigidity of quasi-isometries of horospherical products (MINI TALK)

speaker: Tom Ferragut

abstract: Horospherical products of two Gromov hyperbolic spaces were introduced to unify the construction of metric spaces such as Diestel-Leader graphs, the Sol geometry or treebolic spaces. In this minitalk we will look at their geometry through a description of their geodesics and distances. Then we will get interested in a geometric rigidity property of their quasi-isometries.
