Perhaps you should try some spelling variations:
matematica della » matematica nella, matematiche dalla, matematica da
matematici della » matematica da
matematici per » matematica e
un matematici » un matematico, una matematica, i matematici

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 sfide ((matematica della) OR (matematici della)) ) OR ( lecture notes of the un matematici per )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( lecture notes of the sfide ((matematica della) OR (matematici della)) ) or ( lecture notes of the un matematici per ))".
• Adding a wildcard symbol may retrieve word variants: (( lecture notes of the sfide ((matematica della) OR (matematici della)) ) or ( lecture notes of the un matematici per ))*.
