Perhaps you should try some spelling variations:
"lecture notes of the funcoes matematica della" » "lecture notes of the functions mathematical della", "lecture notes of the functions mathematics della", "lecture notes of the funcoes matematica nella", "lecture notes of the funcoes matematiche dalla", "lecture notes of the funcoes matematica da"
"lecture notes of the la matematica della" » "lecture notes of the la matematica nella", "lecture notes of the la matematiche dalla", "lecture notes of the la matematica da", "lecture notes of the a mathematica della", "lecture notes of the e matematica della", "lecture notes of the della matematica della"
"lecture notes of the la matematici della" » "lecture notes of the la matematici per", "lecture notes of the la matematica da", "lecture notes of the i matematici della", "lecture notes of the a matematica della", "lecture notes of the di matematici della"

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

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