Triangle-Free Coloring in LOCAL via Resilient Lovász Local Lemma
Peter Davies-Peck, Xusheng Zhang
The Lovász Local Lemma (LLL) is a probabilistic tool that has been shown to be of central importance in the study of distributed algorithms. For example, the constructive LLL is kn…
Scaling limits of multi-period distributionally robust optimization problems
Max Nendel, Ariel Neufeld, Kyunghyun Park +1
We examine the scaling limit of multi-period distributionally robust optimization (DRO) problems via a semigroup approach. Each period involves a worst-case maximization over distr…
Hopf-Lax approximation for value functions of Lévy optimal control problems
Michael Kupper, Max Nendel, Alessandro Sgarabottolo
In this paper, we investigate stochastic versions of the Hopf-Lax formula which are based on compositions of the Hopf-Lax operator with the transition kernel of a Lévy process tak…
Discrete approximation of risk-based prices under volatility uncertainty
Jonas Blessing, Michael Kupper, Alessandro Sgarabottolo
We discuss the asymptotic behaviour of risk-based indifference prices of European contingent claims in discrete-time financial markets under volatility uncertainty as the number of…
