多边际最优输运的Monge解和唯一性:费用条件较弱,边际条件较强

Monge solutions and uniqueness in multi-marginal optimal transport: weaker conditions on the cost, stronger conditions on the marginals

Brendan Pass, Adolfo Vargas-Jiménez

摘要:

我们建立了一个一般条件的费用函数获得的唯一性和Monge解决方案的多边际最优输运问题,假设一个给定的收集的边际是绝对连续的局部坐标。当只有第一个边际假设是绝对连续的,我们的条件是等价的分裂集条件在[23]中找到的扭曲。此外,它是满足特殊的费用函数在我们的早期工作[32,33],当绝对连续性施加在某些其他的边缘集合。我们还提出了几个新的例子,费用函数违反了分裂集条件的扭曲,但满足新的条件介绍这里,因此,我们获得蒙赫解决方案和唯一性结果,这些费用函数,在正则性条件下的适当子集的边缘。

英文摘要:

We establish a general condition on the cost function to obtain uniqueness and Monge solutions in the multi-marginal optimal transport problem, under the assumption that a given collection of the marginals are absolutely continuous with respect to local coordinates. When only the first marginal is assumed to be absolutely continuous, our condition is equivalent to the twist on splitting sets condition found in [23]. In addition, it is satisfied by the special cost functions in our earlier work [32, 33], when absolute continuity is imposed on certain other collections of marginals. We also present several new examples of cost functions which violate the twist on splitting sets condition but satisfy the new condition introduced here; we therefore obtain Monge solution and uniqueness results for these cost functions, under regularity conditions on an appropriate subset of the marginals.
