Perhaps you should try some spelling variations:
"lecture notes of the unione matematici della" » "lecture notes of the unione matematica della", "lecture notes of the unione matematica da"
"lecture notes of the unione matematici per" » "lecture notes of the unione matematica per", "lecture notes of the unione matematica e"
"lecture notes of the a matematica della" » "lecture notes of the a matematica nella", "lecture notes of the a matematiche dalla", "lecture notes of the a matematica da", "lecture notes of the a mathematica della", "lecture notes of the la matematica della", "lecture notes of the e matematica della"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("lecture notes of the unione matematici della") OR ("lecture notes of the unione matematici per"))) OR ("lecture notes of the a matematica della")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"lecture notes of the unione matematici della\") OR (\"lecture notes of the unione matematici per\"))) or (\"lecture notes of the a matematica della\"))".
• Removing quotes may allow a broader search: (((( lecture notes of the unione matematici della ) OR ( lecture notes of the unione matematici per ))) or ( lecture notes of the a matematica della )).
• Adding a wildcard symbol may retrieve word variants: (((("lecture notes of the unione matematici della") OR ("lecture notes of the unione matematici per"))) or ("lecture notes of the a matematica della"))*.
