Perhaps you should try some spelling variations:
"interdisciplinary approach mathematics" » "multidisciplinary approach mathematics", "interdisciplinary approaches mathematics", "interdisciplinary approaches mathematical", "interdisciplinary approach automatic"
"interdisciplinary approach mathematical" » "multidisciplinary approach mathematical", "interdisciplinary approaches mathematical", "interdisciplinary appendix mathematical", "interdisciplinary applied mathematical"
"interdisciplinary applied mathematics" » "interdisciplinary analyses mathematics", "interdisciplinary aspects mathematics", "interdisciplinary area mathematics"

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: (((("interdisciplinary approach mathematics") OR ("interdisciplinary applied mathematics"))) OR ("interdisciplinary approach mathematical"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"interdisciplinary approach mathematics\") OR (\"interdisciplinary applied mathematics\"))) or (\"interdisciplinary approach mathematical\"))*".
• Removing quotes may allow a broader search: (((( interdisciplinary approach mathematics ) OR ( interdisciplinary applied mathematics ))) or ( interdisciplinary approach mathematical ))*.
