Perhaps you should try some spelling variations:
"historico por mathematics" » "historico of mathematics", "historico in mathematics", "historico con mathematica", "historico para mathematics", "historia por mathematics", "historico de mathematics"
"history of mathematica" » "history of mathematics", "history con mathematica", "history de mathematica"
"historia y matematicas" » "historia de matematicas", "historia en matematicas", "historia las matematicas"

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 of mathematica\") OR (((\"historia y matematicas\") OR (\"historico por mathematics\"))))~".
• Removing quotes may allow a broader search: (( history of mathematica ) OR ((( historia y matematicas ) OR ( historico por mathematics ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history of mathematica") OR ((("historia y matematicas") OR ("historico por mathematics"))))*.
