...Let us just briefly mention the theoretical importance of the L2 MKP in many different fields such as probability theory and statistics [31], functional analysis [3], kinetic theory (where theL2 Kantorovich distance is closely related to the homogeneous Boltzmann equation of maxwellian molecules and the Fokker-Planck equation [36,22]), atmospheric sciences (where the construction of the semigeostrophic model by Cullen and Purser is based on a variant of the L2 MKP [16,6]), astrophysics [26], porous media equations, Hele-Shaw equations (with the new approach introduced by Otto for dissipative PDEs viewed as gradient flows with respect to the L2 Kantorovich metric [28,29])....

...Let us recall a basic theoretical result on the L2 MKP ([24,8,10], see also [31,21,19]): there is a unique optimal transfer M characterized as the unique map transferring ρ0 to ρT which can be written as the gradient of some convex functionΨ , M(x) = ∇Ψ(x)....
