Speakers: Elisa Calzola (Rome Sapienza), Harry Wells (University College London), Ahmad Zorkot (University of Limoges), E. Carlini (Rome Sapienza), Indranil Chowdhury (Indian Institute of Technology Kanpur), Diogo Gomes (KAUST Saudi Arabia)

Abstract: Mean field games are a system of nonlinear partial differential equations (PDEs) that model Nash equilibria of stochastic differential games involving a large numbers of players. They find applications across many fields, including mathematical biology, engineering, economics, and finance. This minisymposium will present recent developments in the design and analysis of discretisation methods for these problems to address the many numerical challenges encountered, such as structure preservation, first-order systems, nonlocal diffusions, error analysis and convergence rates, and nonsmoothness of the nonlinearities.

Abstract: High-order numerical methods can provide more accurate solutions to PDEs for less computational resources when compared to low order methods for sufficiently smooth solutions. Additionally, hp-methods for mesh-based numerical methods provide a technique for combining high-order approximations in smooth analytical regions with low order approximations near singularities or interfaces. In this minisymposium we aim to discuss recent developments in the implementation and analysis of high-order and hp- methods for PDEs along with techniques for adaptive refinement in hp-methods.
