Talk:Möbius function

Renamed it back to its original name. The argument for the earlier rename is strange ("for harmony with the category with the same name"? Not sure whether such a category should exist... But each specific article should always have the the name which is closest possible to the most "authentic" spelling. AFAIK, it's handled like this on all other international, multi-author encyclopaedias. Other considerations, in favour of simplified names etc., can be taken into account through redirects.) Concerning categories, I added [Category:Arithmetic functions], [Category:Multiplicative functions], [Category:Integer valued functions]. — M. F. Hasler 03:42, 29 January 2013 (UTC)
