I think it would help, for the counterexample, to check whether it is locally integrable, at (0,0). Charles Matthews 22:39, 14 January 2006 (UTC)

I'm very curious, as I know this property as "Young's Theorem," but this is not mentioned by name here. (dphrag 07:19, 14 June 2006 (UTC))

Yeah, I also heard it is called that way. I mentioned this in the article. Oleg Alexandrov (talk) 01:01, 15 June 2006 (UTC)

I removed it. --M1ss1ontom a rs2k4 ^{(T | C | @)} 21:48, 22 June 2006 (UTC)
