A weak transport approach to the Schrödinger-Bass bridge
Manuel Hasenbichler, Gudmund Pammer, Stefan Thonhauser
We study the Schrödinger-Bass problem, a one-parameter family of semimartingale optimal transport problems indexed by , whose limiting regimes interpolate between the classi…

The Martingale Sinkhorn Algorithm
Manuel Hasenbichler, Benjamin Joseph, Gregoire Loeper +2
We develop a numerical method for the martingale analogue of the Benamou--Brenier optimal transport problem, which seeks a martingale interpolating two prescribed marginals which i…
