Perhaps you should try some spelling variations:
sfide matematiche » forme matematiche
vite matematiche » forme matematiche, e mattematiche, vino matematica
matematici della » matematici per, matematica da
i matematici » i mathematics, di matematica, e matematica

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