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