Wasserstein-type concentration inequalities for empirical measures on polish spaces

Yes, there are various results available in more general settings. The typical route would be to combine an upper bound on the expected distance between the law and the empirical measure (like Theorem …

Uniformization/measurable selection theorems

Bogachev's Measure Theory, Vol. 2 Chapter 6, section 9 is a survey of measurable selection theorems written in the 2000s. It mentions a handful of results which were published in the 80s, but nothing …

Are there any results on concentration bounds of Wasserstein distances between empirical mea...

Yes, it turns out you can do better than the triangle inequality in this case. See section 3.1 of "Faster Wasserstein Distance Estimation with the Sinkhorn Divergence".

Are the sublevel sets of Boltzmann entropy compact in Wasserstein distance?

It is known that the sublevel sets of the relative entropy are tight when the reference measure is finite, and in fact are also compact in the topology of setwise convergence (which is stronger than t …

Reference request: "doubly empirical" measure associated to a random measure

I am considering the following type of situation. Suppose we have a random probability measure, by which I mean a probability measure on a space of probability measures atop some Polish space $X$. In …

Projections in infinite dimensional statistical manifolds

This is not a direct answer to your question, but rather a pointer to some literature. The book "Information Geometry" by Ay et al. does generalize a bunch of existing machinery from the finite-dimens …
