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

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 matematiche dalla") OR ("lecture notes of the sfide matematiche dalla"))) OR ("lecture notes of the a matematica dalla")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"lecture notes of the unione matematiche dalla\") OR (\"lecture notes of the sfide matematiche dalla\"))) or (\"lecture notes of the a matematica dalla\"))".
• Removing quotes may allow a broader search: (((( lecture notes of the unione matematiche dalla ) OR ( lecture notes of the sfide matematiche dalla ))) or ( lecture notes of the a matematica dalla )).
• Adding a wildcard symbol may retrieve word variants: (((("lecture notes of the unione matematiche dalla") OR ("lecture notes of the sfide matematiche dalla"))) or ("lecture notes of the a matematica dalla"))*.
