Perhaps you should try some spelling variations:
formeln mathematische » deren mathematische, forderung mathematischer, losen mathematischer
forme matematiche » forma matematica, formed mathematical, forms mathematical
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 ((forme matematiche) OR (formeln mathematische)) 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 ((forme matematiche) OR (formeln mathematische)) dalla ) or ( lecture notes of the i matematici della ))".
• Adding a wildcard symbol may retrieve word variants: (( lecture notes of the ((forme matematiche) OR (formeln mathematische)) dalla ) or ( lecture notes of the i matematici della ))*.
