It is known that for many natural metrics, no coarse embedding of either of these two spaces into Hilbert space exists. Some cases remain open, however. In particular, whether coarse embeddings exist with respect to the p<\/jats:italic>-Wasserstein distance for \n \n $$1\\le p\\le 2$$<\/jats:tex-math>\n \n \n 1<\/mml:mn>\n \u2264<\/mml:mo>\n p<\/mml:mi>\n \u2264<\/mml:mo>\n 2<\/mml:mn>\n <\/mml:mrow>\n <\/mml:math>\n <\/jats:alternatives>\n <\/jats:inline-formula> remains an open question for the space of persistence diagrams and for Wasserstein space on the plane.
