When 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 (P;Q) = sup;˚ Z (y)dQ(y) Z ˚(x)dP(x)
