摘要：

Hitchin representations are a class of representations of surface groups into simple split real Lie groups introduced by Hitchin in the 90's. They have attracted a lot of attention probably because of their remarkable resemblance between the (nowadays called) Hitchin component of \pi_1S with values in G, and the classical Teichmüller space of the surface S.  

In this lecture we will discuss a new proof based on Lusztig's positivity of triples, of a result by Guichard on the classification of Zariski closures of Hitchin representations.
