Perhaps you should try some spelling variations:
"lecture notes of the functions mathematica della" » "lecture notes of the functions mathematical della", "lecture notes of the functions mathematics della", "lecture notes of the function mathematica della", "lecture notes of the functions matematica della", "lecture notes of the functions mathematical delay", "lecture notes of the functions mathematica de"
"lecture notes of the funcoes matematici della" » "lecture notes of the funcoes matematica della", "lecture notes of the functions mathematics della", "lecture notes of the funcoes matematici per", "lecture notes of the funcoes matematica da"
"lecture notes of the la matematiche dalla" » "lecture notes of the la matematica della", "lecture notes of the la matematica nella", "lecture notes of the la matematica dalla", "lecture notes of the las matematicas dalla", "lecture notes of the a 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 funcoes matematici della") OR ("lecture notes of the functions mathematica della"))) OR ("lecture notes of the la matematiche dalla")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"lecture notes of the funcoes matematici della\") OR (\"lecture notes of the functions mathematica della\"))) or (\"lecture notes of the la matematiche dalla\"))".
• Removing quotes may allow a broader search: (((( lecture notes of the funcoes matematici della ) OR ( lecture notes of the functions mathematica della ))) or ( lecture notes of the la matematiche dalla )).
• Adding a wildcard symbol may retrieve word variants: (((("lecture notes of the funcoes matematici della") OR ("lecture notes of the functions mathematica della"))) or ("lecture notes of the la matematiche dalla"))*.
