Abstract

We prove that OTη(T)Tlog2T\mathsf{OT}_\eta(T)\ll T\log^2 T unconditionally via a band-limited test scheme with Fej\'er averaging. The approach normalizes f^1=Θ(T1)\|\widehat f\|_1=\Theta(T^{-1}) to ensure h1T\|h\|_1\asymp T and h^11\|\widehat h\|_1\ll 1, and applies an L1L^1-controlled smoothed explicit formula to bound the error terms. As a result, the prime--zero optimal transport distance admits the baseline Tlog2TT\log^2 T upper bound without additional assumptions.
