Perhaps you should try some spelling variations:
funcoes matematica » functions mathematical, functions mathematics
matematica italian » matematica italiana, matematica alla, mathematical vitality
unione matematica » una matematica, urbino matematica, vino matematica
suono matematica » secolo matematica, una matematica, vino 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 ((unione matematica) OR (funcoes matematica)) italian ) OR ( lecture notes of the suono matematica italian )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( lecture notes of the ((unione matematica) OR (funcoes matematica)) italian ) or ( lecture notes of the suono matematica italian ))".
• Adding a wildcard symbol may retrieve word variants: (( lecture notes of the ((unione matematica) OR (funcoes matematica)) italian ) or ( lecture notes of the suono matematica italian ))*.
