Perhaps you should try some spelling variations:
"interaction theory: advances and applications" » "intersection theory: advances and applications", "introduction theory: advances and applications", "interactive theorem: advances and applications"
"operation theory: advances and applications" » "operations theory: advances and applications", "operator theory: advances and applications", "iteration theory: 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 ((("interaction theory: advances and applications") OR ("integration theory: advances and applications")))).
• Removing quotes may allow a broader search: (( operation theory: advances and applications ) or ((( interaction theory: advances and applications ) or ( integration theory: advances and applications )))).
• Adding a wildcard symbol may retrieve word variants: (("operation theory: advances and applications") or ((("interaction theory: advances and applications") or ("integration theory: advances and applications"))))*.
