报告题目一：Inverse problems for mean field games 

  报告摘要：The theory of mean field games studies the limiting behaviours of large systems where the agents interact with each other in a certain symmetric way. It has rapidly developed into one of the most significant tools towards the study of the Nash equilibrium behaviour of large systems. The mathematical study of mean field games has attracted considerable interest in the scientific community. I shall talk about our recent advances on the mathematical understanding of the mean field game theory from the perspective of inverse problems.

  报告题目二：Inverse problems for nonlinear progressive waves

  报告摘要：Infrasound refers to sound waves with frequencies below the audible range of human hearing. It continues to receive significant attention in the literature due to their key role in a variety of applications of practical importance. In this talk, I shall discuss our recent results on the infrasonic inversions.
