DESCRIPTION:Misha Kapovich in collaboration with B. Leeb and J. Porti and 
 also Dey developed a geometric theory of Anosov representations into simpl
 e Lie groups of higher rank. Among others\, they discovered the importance
  of studying such representations using invariant Finsler metrics.&nbsp\;\
 nBest known such representations are Hitchin surface group representations
  into SL(n\,R). For so-called Hitchin grafting representations we discuss 
 a different geometric viewpoint which can be thought of as a geometric int
 erpretation of Fock Goncharov positivity. It can be used to understand the
  geometry of these representations explicity. This is based on joint work 
 with Pierre-Louis Blayac and Theo Marty.&nbsp\;
