preprintarXivSep 22, 2026Relative Wasserstein Angle and the Problem of the $W_2$-Nearest Gaussian Distribution
Building on the cone structure of the relative translation invariant quadratic Wasserstein $(RW_2)$ space, we define two geometric quantities---the \emph{relative Wasserstein angle} and the \emph{orthogonal projection distance}
