CONFERENCE
Conference on Noncommutative Geometry

November 2 - 6, 2015
One of the aims of noncommutative geometry is to generalize the main tools of geometry to a class of regular enough C*-algebras that can be considered as «noncommutative spaces» and  thus get applications in geometry, analysis, number theory and quantum mechanics. This involves many different tools and questions. This conference will make an overview of some of them :
  • Index theorems and applications.
  • Applications of cohomological theories. Baum-Connes conjecture.
  • Geometric group theory and Von Neumann Algebras.
  • Quantum Groups, subfactors.
  • Groupoids and applications.
We intend to spend one day on each of the preceding themes. An expert of each theme will be asked to give an overview of the subject, and this will be followed by more recent results or particularly important results. The aim is to get an overview on the recent progress on all of these themes together with a glimpse of their interactions.
