Establishes a general lower bound of order ε^{1/(d+2)} on the localization rate of QOT optimizers around the Monge coupling in directed Hausdorff distance, with sharper affine-case tube bounds.
Estimators for transport-growth pairs in unbalanced OT achieve minimax optimal rates, supported by a value-based stability reduction through a UOT gap condition.
The paper characterizes stability of the Kim-Milman flow map with respect to target measure variations measured in relative Fisher information.
