A grid-sketching technique enables ε-accurate estimation of W₂² between α-Hölder smooth distributions on (0,1)^d in time ε^{-max(2, (d+1+o(1))/(1+α))}.
Constructs solutions to Monge-Ampère equations with singular measure components on low-codimension sets, studies their regularity, and motivates the work with optimal transport examples.
