Perhaps you should try some spelling variations:
forme matematiche » formeln mathematische, formed mathematical, forms mathematical
forma matematica » formal mathematical, formal mathematics, forms mathematical
matematici della » matematici per, matematica da
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 ((forme matematiche) OR (forma matematica)) dalla ) OR ( lecture notes of the un matematici della )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( lecture notes of the ((forme matematiche) OR (forma matematica)) dalla ) or ( lecture notes of the un matematici della ))".
• Adding a wildcard symbol may retrieve word variants: (( lecture notes of the ((forme matematiche) OR (forma matematica)) dalla ) or ( lecture notes of the un matematici della ))*.
