DESCRIPTION:Speakers: Charles Reid (MPI Leipzig)\n\nA hyperbolic structure
  on a surface is captured by a representation of the fundamental group int
 o PSL(2\,R). Higher rank Teichmüller theory aims to go beyond hyperbolic 
 geometry by studying representations into bigger lie groups\, for instance
  PSL(n\,R). I will discuss a "higher" version of one piece of hyperbolic g
 eometry--Thurston's compactification of Teichmüller space. Boundary point
 s of this compactification are measured laminations\, certain objects gene
 ralizing simple closed curves. I will discuss compactifications of certain
  higher Teichmüller spaces where we will see closed curves with more intr
 icate restrictions on self-intersection appearing in the boundary.\n\nhttp
