DESCRIPTION:The Langlands correspondence was originally formulated as a co
 njectural  link between representations of Galois groups of number fields
  and  automorphic data. Translating these conjectures into statements for
   function fields of curves many of the objects admit natural geometric 
  interpretations and the geometry then helps to prove results. For  exam
 ple some expected invariance properties of functions turned into  descent
  properties of sheaves that sometimes follow from topological  considerat
 ions. In this talk we will try to give some background on the  first exam
 ples ($GL_1$ and $GL_2$) where this had been observed first by  Deligne a
 nd Drinfeld and introduce some of the structures that occur in the more g
 eneral results.\n\nhttps://indico.math.cnrs.fr/event/16246/
