Perhaps you should try some spelling variations:
"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 applied mathematics") OR ("interdisciplinary approach mathematical"))*.
• Removing quotes may allow a broader search: (( interdisciplinary applied mathematics ) or ( interdisciplinary approach mathematical ))*.
