Perhaps you should try some spelling variations:
"functions of a complete variable" » "functions of a complex variable", "functions of a complete verifiable", "functions of a complex variables"
"functions of a komplexe variable" » "functions of a komplexen variablen", "functions of a complex variable", "functions of a complex variables", "functions of a5 komplexe variable", "functions of 5 komplexe variable", "functions of 1 komplexe variable"
"functions of 3 komplexe variable" » "functions of 3 komplexen variablen", "functions of 3 complex variable", "functions of 3 complex variables", "functions of 5 komplexe variable"

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 komplexe variable") OR ("functions of 3 komplexe variable")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"functions of a complete variable\") or (((\"functions of a komplexe variable\") OR (\"functions of 3 komplexe variable\"))))".
• Removing quotes may allow a broader search: (( functions of a complete variable ) or ((( functions of a komplexe variable ) OR ( functions of 3 komplexe variable )))).
• Adding a wildcard symbol may retrieve word variants: (("functions of a complete variable") or ((("functions of a komplexe variable") OR ("functions of 3 komplexe variable"))))*.
