Perhaps you should try some spelling variations:
"operation theory: advances and applications" » "operations theory: advances and applications", "operator theory: advances and applications", "generation theory: advances and applications"
"iteration theory: advances and applications" » "integration theory: advances and applications", "interaction theory: advances and applications", "interpolation theory: advances and applications"
"vibration theory: advances and applications" » "vibration test: advances and applications"

Try widening your search to All Fields.

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: (("operation theory: advances and applications") OR ((("iteration theory: advances and applications") OR ("vibration theory: advances and applications")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"operation theory: advances and applications\") or (((\"iteration theory: advances and applications\") OR (\"vibration theory: advances and applications\"))))".
• Removing quotes may allow a broader search: (( operation theory: advances and applications ) or ((( iteration theory: advances and applications ) OR ( vibration theory: advances and applications )))).
• Adding a wildcard symbol may retrieve word variants: (("operation theory: advances and applications") or ((("iteration theory: advances and applications") OR ("vibration theory: advances and applications"))))*.
