报告摘要:We develop a new flow dynamic approach for Wasserstein gradient flows. Motivatied by the classic JKO scheme, we develop a new class of Lagrangian schemes which only need to solve minimization problems with respective to displacement instead of density and velocity. The new approach can effectively capture the movement of the trajectory of meshes, and also can automatically preserve the nice properties of Wasserstein gradient flow structure, for example, positivity-preserving, mass conserving and energy dissipation.Numerical experiments are shown in 1D and 2D for Keller-Segel equations,Focker-Plancker equations, Porous medium equations.
