The Fatou Closedness under Model Uncertainty

Functional Analysis 2018-10-11 v6 Probability Mathematical Finance

Abstract

We provide a characterization in terms of Fatou closedness for weakly closed monotone convex sets in the space of P\mathcal{P}-quasisure bounded random variables, where P\mathcal{P} is a (possibly non-dominated) class of probability measures. Applications of our results lie within robust versions the Fundamental Theorem of Asset Pricing or dual representation of convex risk measures.
