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 matematici per", "lecture notes of the unione matematica da"
"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 _ matematica della"
"lecture notes of the e matematica della" » "lecture notes of the e matematica nella", "lecture notes of the e matematiche dalla", "lecture notes of the e matematica da", "lecture notes of the della 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 a matematica della") OR ("lecture notes of the e 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 a matematica della\") OR (\"lecture notes of the e matematica della\"))))".
• Removing quotes may allow a broader search: (( lecture notes of the unione matematici della ) or ((( lecture notes of the a matematica della ) OR ( lecture notes of the e matematica della )))).
• Adding a wildcard symbol may retrieve word variants: (("lecture notes of the unione matematici della") or ((("lecture notes of the a matematica della") OR ("lecture notes of the e matematica della"))))*.
