Perhaps you should try some spelling variations:
"historia de mathematica" » "historia de matematica", "historia de matematicas", "historia e matematica"
"history en matematica" » "history en matematicas", "history la matematica", "history el matematico", "historia en matematica", "history and matematica", "history of matematica"
"historia y mathematica" » "historia y matematica", "historia y matematicas", "historia y matematico"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("history en matematica") OR ((("historia y mathematica") OR ("historia de mathematica"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"history en matematica\") OR (((\"historia y mathematica\") OR (\"historia de mathematica\"))))*".
• Removing quotes may allow a broader search: (( history en matematica ) OR ((( historia y mathematica ) OR ( historia de mathematica ))))*.
