Perhaps you should try some spelling variations:
"appendix mathematical sciences" » "appendix mathematics sciences", "appendix mathematical geosciencess", "appendix mathematical finances"
"appendix mathematical science" » "appendix mathematics science", "appendix mathematical geosciences", "appendix mathematical finance"

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