Perhaps you should try some spelling variations:
"functions of a complete variable" » "functions of a complete verifiable", "functions of a complex variables", "functions of a template variable"
"functions of 5 komplexe variable" » "functions of 5 komplexen variablen", "functions of 5 complex variables", "functions of 3 komplexe variable"
"functions of a complex variable" » "functions of a complex variables"

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: (((("functions of a complete variable") OR ("functions of a complex variable"))) OR ("functions of 5 komplexe variable")).
• Removing quotes may allow a broader search: (((( functions of a complete variable ) or ( functions of a complex variable ))) or ( functions of 5 komplexe variable )).
• Adding a wildcard symbol may retrieve word variants: (((("functions of a complete variable") or ("functions of a complex variable"))) or ("functions of 5 komplexe variable"))*.
