abstract = {
Given two measured spaces $(X,\mu)$ and $(Y,\nu)$, and a third space Z,
given two functions u(x,z) and v(x,z), we study the problem of finding two
maps $s:X\rightarrow Z$ and $t:Y\rightarrow Z$ such that the images $s(\mu)$
and $t(\nu)$ coincide, and the integral $\int_\{X\}u(x,s(x))d\mu-\int
_\{Y\}v(y,t(y))d\nu$ is maximal. We give condition on u and v for which
there is a unique solution.
