Perhaps you should try some spelling variations:
"appendices mathematics science" » "appendices mathematical science", "appendix mathematics science", "appendices kinematics science", "appendices mathematical sciences"
"based mathematical finances" » "based mathematical finance", "based mathematical financial", "based mathematical advances", "basic mathematical finances"

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: "((\"based mathematical finances\") OR (\"appendices mathematics science\"))".
• Removing quotes may allow a broader search: (( based mathematical finances ) OR ( appendices mathematics science )).
• Adding a wildcard symbol may retrieve word variants: (("based mathematical finances") OR ("appendices mathematics science"))*.
