A relationship between two sided discounted singular control problems and Dynkin games is established for real valued L\'evy processes. In addition, the solution of a two-sided ergodic singular control problem is obtained as the limit of the corresponding solution of the discounted one. With these results, we conclude that the optimal controls within the class of cadlag strategies can be in fact found in the class of reflecting barriers controls for both problems, and solved through some deterministic equations. To illustrate the results, three examples are given: compound Poisson processes with two-sided exponential jumps with and without Gaussian component, and stable processes.

  1. Mean-Field Games with two-sided singular controls for L\'evy processes

    math.OC 2025-05 conditional novelty 6.0 of 10

    Existence of mean-field game equilibria for two-sided singular control of Lévy processes is established via a Brouwer fixed point, with an ergodic limit and finite-player approximation.
