DESCRIPTION:\n	Title: Discrete subgroups of Lie groups and geometric structu
 res.\n\nAbstract: Discrete subgroups of Lie groups play a fundamental role
  in several areas of mathematics. Discrete subgroups of SL(2\,R) are well 
 understood\, and classified by the geometry of the corresponding hyperboli
 c surfaces. On the other hand\, discrete subgroups of SL(n\,R) for n>2\, b
 eyond lattices\, remain quite mysterious. While lattices in this setting a
 re rigid\, there also exist more flexible 'thinner' discrete subgroups\, w
 hich may have large and interesting deformation spaces (some of them with 
 topological and geometric analogies to the Teichmüller space of a surface\
 , giving rise to so-called 'higher Teichmüller theory'). We will survey re
 cent progress in constructing and understanding such discrete subgroups fr
 om a geometric and dynamical viewpoint.\n
