DESCRIPTION:Eleonora Anna Romano (Università di Genova)\nIn this talk we 
 present some recent results on complex  smooth Fano varieties. To this en
 d\, we first recall an invariant introduced by Casagrande\, called Lefsche
 tz defect. We review the literature to deduce that all Fano manifolds with
  Lefschetz defect greater than three are well known. Then we focus on the 
 case in which the Lefschetz defect is equal to three\, by discussing a str
 ucture theorem for such varieties. As an application\, we use this result 
 to classify all Fano 4-folds with Lefschetz defect equal to three: there a
 re 18 families\, among which 14 are toric. This is a joint work with C. Ca
 sagrande and S. Secci.
