DESCRIPTION:Riccardo Ontani\nMany interesting varieties can be built as GI
 T quotients of linear spaces by actions of reductive groups\, a big family
  of examples being given by quiver varieties. In this talk we will describ
 e a localisation formula (due to Jeffrey and Kirwan) for computing integra
 ls over this kind of quotients. If the quotient variety is not proper but 
 it admits a circle action with proper fixed locus\, we can still define th
 e integrals by localisation and obtain a formula for them.
