Perhaps you should try some spelling variations:
"historia in mathematical" » "historia in mathematics", "historia en matematicas", "historia en matematica", "historia en mathematical", "historia un mathematical", "historia ii mathematical"
"history of matematica" » "history of mathematics", "history la matematica", "history de matematica"
"history y matematica" » "history y matematicas", "history y matematico", "history la matematica", "history a matematica", "historia y matematica"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history y matematica\") OR (\"history of matematica\"))) OR (\"historia in mathematical\"))~".
• Removing quotes may allow a broader search: (((( history y matematica ) OR ( history of matematica ))) OR ( historia in mathematical ))~.
• Adding a wildcard symbol may retrieve word variants: (((("history y matematica") OR ("history of matematica"))) OR ("historia in mathematical"))*.
