Couplings Farthest from the Independent Gaussian

Stefan Schrott

Motivated by Wasserstein measures of dependence, we study the largest possible 2-Wasserstein distance between a joint distribution and the product of its prescribed marginals. For…

A Brenier Theorem on and Applications to Adapted Transport

Mathias Beiglböck, Gudmund Pammer, Stefan Schrott

We develop Brenier theorems on iterated Wasserstein spaces. For a separable Hilbert space and , we construct a full-support probability on $P_2^{N}(H)= P_2(... P_2…

The Fundamental Theorem of Weak Optimal Transport

Mathias Beiglböck, Gudmund Pammer, Lorenz Riess +1

The fundamental theorem of classical optimal transport establishes strong duality and characterizes optimizers through a complementary slackness condition. Milestones such as Breni…

The Wasserstein Space of Stochastic Processes in Continuous Time

Daniel Bartl, Mathias Beiglböck, Gudmund Pammer +2

Researchers from different areas have independently defined extensions of the usual weak convergence of laws of stochastic processes with the goal of adequately accounting for the…

A Probabilistic View on the Adapted Wasserstein Distance

Mathias Beiglböck, Susanne Pflügl, Stefan Schrott

Causal optimal transport and adapted Wasserstein distance have applications in different fields from optimization to mathematical finance and machine learning. The goal of this art…

Representing General Stochastic Processes as Martingale Laws

Mathias Beiglböck, Gudmund Pammer, Stefan Schrott +1

Random variables , are 'probabilistically equivalent' if they have the same law. Moreover, in any class of equivalent random variables it is easy to select canonical r…

On Strassen's Theorem for support functions

Stefan Schrott, Daniel Toneian

Strassen established that there exists a two step martingale with marginal distributions , if and only if , are in convex order. Recently Choné-Gozlan-Kramarz obtaine…

Denseness of biadapted Monge mappings

Mathias Beiglböck, Gudmund Pammer, Stefan Schrott

Adapted or causal transport theory aims to extend classical optimal transport from probability measures to stochastic processes. On a technical level, the novelty is to restrict to…
