This is the text of a talk given at the XVII Convegno dellUnione Matematica Italiana held at Milano, September 8-13, 2003. I would like to thank Angelo Lopez and Ciro Ciliberto for the kind invitation to the conference. I survey some numerical conjectures and theorems concerning relations between the index, the pseudo-index and the Picard number of a Fano variety. The results I refer to are contained in the paper [3], wrote in collaboration with Bonavero, Debarre and Druel.
Questa nota è il testo di una conferenza tenuta al XVII Convegno dell'Unione Matematica Italiana, tenutosi a Milano, 8-13 settembre 2003. Parlo di alcune congetture e teoremi sulle relazioni tra l'indice, lo pseudo-indice e il numero di Picard di una varietà di Fano. I risultati in questione fanno parte di un lavoro in collaborazione con Bonavero, Debarre e Druel.
