Restoring Wasserstein Rigidity with a single point

Zoltán M. Balogh, Eric Ströher, Dániel Virosztek

We consider isometrically flexible Wasserstein spaces and demonstrate that adding a single point to the underlying metric space makes these Wasserstein spaces rigid.

Wasserstein Rigidity over $R^{n}$ with smooth norms

Zoltán M. Balogh, Eric Ströher, Tamás Titkos +1

We study $p -$ Wasserstein spaces $W_{p} (R^{n}, d_{N})$ over $R^{n}$ equipped with a norm metric $d_{N}$ . We show that, if the norm is smooth enough, then the Wass…

Rigid and flexible Wasserstein spaces

Zoltán M. Balogh, Eric Ströher, Tamás Titkos +1

In this paper, we study isometries of $p$ -Wasserstein spaces. In our first result, for every complete and separable metric space $X$ and for every $p \geq 1$ , we construct a metric s…
