WebWhen p= 1 this is also called the Earth Mover distance. The minimizer J (which does exist) is called the optimal transport plan or the optimal coupling. In case there is an optimal transport map T then J is a singular measure with all its mass on the set f(x;T(x))g. It can be shown that Wp p Webthe distances w e de ne are not metric. Concerning this p oin t, w e refer to Tv ersky's discussion [28]ofthe non-metric nature of p erceptual distances.
