Huh?

- That's what mathematical definitions look like! The article needs a qualitative description about what this metric is in the lead, and some discussion of applications, but the definition is as good as it's going to get, I expect. --Tango (talk) 17:29, 29 January 2008 (UTC)
Equivalent names
I forgot the references (e.g. some survey about Kantorovitch), but this "Hutchinson metric" appears in the literature under several names e.g. Monge-Kantorovitch metric, since it plays some role in the transportation problem and Monge-Ampere equation. Barnsley & others used this I think after Hutchinson papers, hence the new tradition. --Megaloxantha (talk) 03:02, 31 December 2008 (UTC)
- Yes, that's my sense of the history, too. I believe it's most properly called the Wasserstein metric (look at the dual representation of W1). It's also called the Kantorovich-Rubinstein-Wasserstein metric, the Fortet-Mourier norm and the earth mover's distance.75.168.185.28 (talk) 03:20, 21 May 2009 (UTC)Craig
