WebLook at optimal transport on the 2-sphere. = normalized Riemannian density. Take 0, 1two disjoint congruent blobs. Then U ( 0) = U ( 1). Optimal transport from 0to 1goes along geodesics. Positive curvature gives focusing of geodesics. Take snapshot at time t. Intermediate-time blob tis more spread out, so it’s more uniform w.r.t. . Web0 <1. A geodesic, also called an optimal transport path, in this space is a weighted directed graph whose edges are geodesic segments. Moreover, when Xis a geodesic metric space of curvature bounded above, we nd in x2, a universal lower bound depending only on the parameter for each comparison angle between edges of any optimal transport path.
