By discretizing an argument of Kislyakov, Naor and Schechtman proved that the 1-Wasserstein metric over the planar gridhas-distortion bounded below by a constant multiple of. We provide a new “dimensionality” interpretation of Kislyakov’s argument, showing that ifis a sequence of graphs whose isoperimetric dimension and Lipschitz-spectral dimension equal a common number, then the 1-Wasserstein metric overhas-distortion bounded below by a constant multiple of. We proceed to compute these dimensions for-powers of certain graphs. In particular, we get that the sequence of diamond graphshas isoperimetric dimension and Lipschitz-spectral dimension equal to 2, obtaining as a corollary that the 1-Wasserstein metric overhas-distortion bounded below by a constant multiple of. This answers a question of Dilworth, Kutzarova, and Ostrovskii and exhibits only the third sequence of-embeddable graphs whose sequence of 1-Wasserstein metrics is not-embeddable. References
