1-Wasserstein distance between two multivariate normal
The $p$-Wasserstein between two measures $\nu_1$ and $\nu_2$ on $X$ is given by
$$d_p(\nu_{1},\nu_{2})=\left(\underset{\pi\in\Gamma(\nu_{1},\nu_{2})}{\inf}\int_{\mathbf{\mathcal{X}}^{2}}d(x,y)^p\pi(dx,...

Semi-discrete Wasserstein distance to uniform
Does the $p$-Wasserstein distance have a simpler expression when applied to these two distributions :
A uniform distribution on $[0,1]^d$
A discrete distribution with $N$ equally-weighted point mass ...
