SUMMARY:Workshop / Seminar:Non-positively curved spaces
DESCRIPTION:The CAT(0) inequality says that in non-positively curved spaces triangles are no fatter than the Euclidean ones. The richest examples are symmetric spaces of non-compact type\, which carry Riemannian\, CAT(0)\, and Lie group structures at once. Using SL(n\,\R)/SO(n) as a running example\, I will explain why flats are important\, and how to describe points at infinity in those spaces.  Then I'll say a bit about some work on boundaries of horospheres\, and end with something hopefully interesting: dynamics on those spaces and how we use them to get counting results.
