DESCRIPTION:Maximal representations are an instance of the so-called highe
 r Teichmüller theory: they form families of discrete subgroups of Sp(2n\,
 R)\, a higher rank generalization of PSl(2\,R)\, isomorphic to the fundame
 ntal group of a surface\, that share many common features with holonomies 
 of hyperbolizations. I will discuss joint work with Marc Burger\, Alessand
 ra Iozzi and Anne Parreau\, in which we study actions on affine buildings 
 arising as ultralimits of maximal representations and observe a clear dist
 inction between phenomena already present in the boundary of the Teichmül
 ler space and new flat features.\n
