Perhaps you should try some spelling variations:
"functions of a complete verifiable" » "functions of a complete decidable", "functions of a complete verification", "functions of a computing verifiable"
"functions of a complete variable" » "functions of a complex variable", "functions of a komplexe variable", "functions of a complex variables"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"functions of a complete variable\") OR (\"functions of a complete verifiable\"))".
• Removing quotes may allow a broader search: (( functions of a complete variable ) OR ( functions of a complete verifiable )).
• Adding a wildcard symbol may retrieve word variants: (("functions of a complete variable") OR ("functions of a complete verifiable"))*.
