Regularity of Kantorovich potentials for general cost function

I know De Philippis and Figalli have a paper studying the regularity of the Kantorovich potential. In Theorem 3.3, the authors show that the potential is $C^{k+2, \beta}$ if the density functions of ...

Quantitative bound on Wasserstein distances by $L^p$ distances?

Given two smooth probability densities $f$ and $g$ on $\mathbb{R}$ (or $\mathbb{R}_+$) with finite $p$-th moments. I am wondering if anyone is aware of some explicit upper bound on $W_p(f,g)$ in terms ...

What is the p-th moment finite in the definition of Wasserstein space?

I am confused about the following notation: For a simple case, let $X=R^d$ or $X=R$. What dose $$ \int_X \|x\|^pd\mu(x) $$ mean for a Borel probability measure $\mu$? For $X=R$, then $x\in R$ is a 1-...
