SUMMARY:Cristobal RIVAS (Departamento de Matemática de la Universidad de C
 hile): Smoothing group of homeomorphisms of the real line: the case of Bau
 mslag-Solitar groups
DESCRIPTION:Cristobal RIVAS: Given a group of homeomorphisms of the real li
 ne\, a natural problem is to try to understand when this group is conjugat
 e to a group of diffeomorphisms\, and also to elucidate the optimal regula
 rity within the conjugacy class. This program has shown to be fruitful in 
 the class of abelian\, and nilpotent\, groups as well as for some families
  of right-angled Artin groups. In this talk\, I will report on a recent pr
 oject joint with Franco Gomez\, where we address this problem for the case
  of the Baumslag-Solitar groups BS(m\,n).
