Perhaps you should try some spelling variations:
"based mathematical geosciences" » "based mathematical sciences", "based mathematics science"
"based mathematical science" » "based mathematical sciences", "based mathematics science", "based mathematical finance"
"basic mathematical science" » "basic mathematical sciences", "basic mathematics science", "basic mathematical finance"

Try widening your search to All Fields.

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: (((("based mathematical science") OR ("basic mathematical science"))) OR ("based mathematical geosciences")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"based mathematical science\") OR (\"basic mathematical science\"))) or (\"based mathematical geosciences\"))".
• Removing quotes may allow a broader search: (((( based mathematical science ) OR ( basic mathematical science ))) or ( based mathematical geosciences )).
• Adding a wildcard symbol may retrieve word variants: (((("based mathematical science") OR ("basic mathematical science"))) or ("based mathematical geosciences"))*.
