Abstract:

This is conceived both as a survey paper and a research paper on the theory of optimal transportation of mass, with special emphasis on the case cost=distance. Concerning the general theory, we show a duality formula under quite general growth conditions on the cost, providing also a counterexample. Conserning the case cost=distance, we revisit several recent papers on this argument (starting from Sudakov's one) and using some tools from the theory of $\Gamma$-convergence we provide general existence and stability results for the problem.
