Markov-Nash equilibria in mean-field games under model uncertainty

J Langner, A Neufeld, K Park - arXiv preprint arXiv:2410.11652, 2024 - arxiv.org
We propose and analyze a framework for mean-field Markov games under model
uncertainty. In this framework, a state-measure flow describing the collective behavior of a …

Bounding the Difference between the Values of Robust and Non-Robust Markov Decision Problems

A Neufeld, J Sester - arXiv preprint arXiv:2308.05520, 2023 - arxiv.org
In this note we provide an upper bound for the difference between the value function of a
distributionally robust Markov decision problem and the value function of a non-robust …
