Example TakeN∑N∑f + = δ pi f − = δ ni .i=1i=1Then the optimal Monge cost is given by theminimal connection of the p i with the n i .Relaxed formulation (due to Kantorovich):consider measures γ on X × X• γ is an admissible transport plan ifπ # 1 γ = f + and π # 2 γ = f − .• Transport plans γ that are concentratedon γ-measurable graphs are actually transportmaps T : X → X, via the equalityγ = (Id × T ) # f + .5
