Abstract:
The paper is devoted to the study of the Kantorovich optimal transportation problem
with nonlinear cost functional generated by a cost function depending on the conditional
measures of the transport plan.
The case of a cost function nonconvex in the second argument is considered.
It is proved that this nonlinear Kantorovich problem with general cost function on a Souslin space
can be reduced to the same problem with a convex cost function.
