The object of this paper is to study estimates of for small . Here is the Wasserstein metric on positive measures, , μ is a probability measure and ν a signed, neutral measure (). In [16] we proved uniform (in ϵ) estimates for provided can be controlled in terms of , for any smooth function ϕ.
In this paper we extend the results to the case where such a control fails. This is the case where, e.g., μ has a disconnected support, or the dimension d of μ (to be defined) is larger or equal to .
In the latter case we get such an estimate provided for . If we get a log-Lipschitz estimate.
As an application we obtain Hölder estimates in for curves of probability measures which are absolutely continuous in the total variation norm.
In case the support of μ is disconnected (corresponding to ) we obtain sharp estimates for (“optimal teleportation”):
