Arithmetic Groups and Automorphic Forms

 

Vienna, Austria, Erwin Schrödinger International Institute for Mathematical Physics

January 27 - February 2, 2002

 

 

 

The workshop will focus on recent developments in the theory of automorphic forms, particularly those involving interactions with geometry, number theory and representation theory. It is intended to include the following topics:

  1. the interplay between local representation theory and its global applications in the theory of automorphic forms, especially Langlands functoriality.
  2. Arthur-Selberg and topological trace formulas, in particular geometric aspects in the use of these trace formulas for constructing automorphic forms.
  3.  

  4. cohomology of arithmetic groups as a tool in studying possible relations between automorphic forms and the arithmetic of algebraic varieties resp. the geometry of locally symmetric spaces.
