Existence of Bass martingales and the martingale BenamouBrenier problem in

Julio Backhoff-Veraguas, Mathias Beiglböck, Walter Schachermayer +1

In classical optimal transport, the contributions of BenamouBrenier and McCann regarding the time-dependent version of the problem are cornerstones of the field and form the bas…

A regularized Kellerer theorem in arbitrary dimension

Gudmund Pammer, Benjamin A. Robinson, Walter Schachermayer

We present a multidimensional extension of Kellerer's theorem on the existence of mimicking Markov martingales for peacocks, a term derived from the French for stochastic processes…

Faking Brownian motion with continuous Markov martingales

Mathias Beiglböck, George Lowther, Gudmund Pammer +1

Hamza-Klebaner posed the problem of constructing martingales with Brownian marginals that differ from Brownian motion, so called fake Brownian motions. Besides its theoretical appe…

Convergence of Optimal Expected Utility for a Sequence of Binomial Models

Friedrich Hubalek, Walter Schachermayer

We analyze the convergence of expected utility under the approximation of the Black-Scholes model by binomial models. In a recent paper by D. Kreps and W. Schachermayer a surprisin…
