Gaussian Optimal Transport Beyond Brenier's Theorem
Ho Yun, Yoav Zemel
We explore the geometry of the Bures-Wasserstein space for potentially degenerate Gaussian measures on a separable Hilbert space. In this general setting, the optimal transport map…

Non-injectivity of Bures--Wasserstein barycentres in infinite dimensions
Yoav Zemel
We construct a counterexample to the injectivity conjecture of Masarotto et al (2018). Namely, we construct a class of examples of injective covariance operators on an infinite-dim…
