Hausdorff distance is a lower (or upper bound) for what probability metric?
A general note is that the answer depends heavily on the properties of $\mu$.
First a note that in general $d_H(A,B) \not \le C \cdot W_p(\mu|_A,\mu|_B)$ for $p\in[1,\infty)$ and some $C>0$. Though …

Effect of perturbing the atoms of a measure on the Wasserstein distance
Without further constraints this is not true and easy to see if $X$ is Euclidean: Let $\Gamma$ be the support of an optimal coupling between $G$ and $G'$. If for fixed $y\in p_2(\Gamma)$ the set $\{x …

Kantorovich duality with pseudometrics
Yes the Kantorovich Duality holds for continuous cost functions by following the proof in Villani's book without any change. The proof for general cost functions needs compactness of the set of coupli …

Monge-Kantorovich duality with a $\{0,1\}$ cost function
The strong Kantorovich duality, i.e. the existence of dual solutions, holds whenever $c$ is lower semicontinuous and real-valued, and the optimal coupling has finite cost, see Theorem 5.10(ii) in Vill …

Is there a coupling that induces a given coupling via a transition kernel?
It's not true. If $\mu \mapsto \tilde\mu$ is injective and $X$ has at least two points then the transition kernels have to be deterministic, i.e. there is a measurable map $T:X\to Y$ such that $\kappa …
