The goal of the conference “Numerical methods for optimal transport problems, mean field games, and multi-agent dynamics” is to share and discuss the advances in numerical techniques for the resolution of optimal transport problems, mean field games, and multi-agent dynamics. Several methodologies have been developed in parallel in these fields in the last years, which opens the door to new collaborations because of the relations among the three topics. We expect to motivate these collaborations via plenary talks of experts in the three fields, thematic sessions, and a summer school to incorporate students in order to extend the arising connections.
