Infinite-body optimal transport with Coulomb Cost [PDF]
, 2013 We introduce and analyze symmetric infinite-body optimal transport (OT) problems with cost function of pair potential form. We show that for a natural class of such costs, the optimizer is given by the independent product measure all of whose factors are
