Perhaps you should try some spelling variations:
"appendix mathematical science" » "appendix mathematical sciences", "appendix mathematical geosciences", "appendix mathematical finance"
"appendix mathematics science" » "appendices mathematics science", "appendix mathematische science", "appendix mathmatical science", "appendix mathematical sciences"

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