Event description: 

We study quasi-isometric embeddings of higher
rank symmetric spaces into one another. This generalizes
both Mostow-Margulis rigidity and the rigidity of self-quasi-isometries
of these spaces (Kleiner-Leeb, Eskin-Farb). I will present some
rigidity results (which were to be expected) as well as some
surprising examples. I will end the talk with several open
problems. This is joint work with Kevin Whyte.
