非线性Fokker-Planck方程周期解的存在性、稳定性和正则性

Existence, stability and regularity of periodic solutions for nonlinear Fokker-Planck equations

Eric Luçon, Christophe Poquet

摘要:

本文考虑一类描述无穷总体单元在平均场相互作用下动力学行为的非线性Fokker-Planck方程。依靠慢-快的观点和近似不变流形的理论,我们得到了一个稳定的周期解的PDE的存在性,由概率测度。此外,我们建立了在该周期解的邻域内的光滑等时映射的存在性。

英文摘要:

We consider a class of nonlinear Fokker-Planck equations describing the dynamics of an infinite population of units within mean-field interaction. Relying on a slow-fast viewpoint and on the theory of approximately invariant manifolds we obtain the existence of a stable periodic solution for the PDE, consisting of probability measures. Moreover we establish the existence of a smooth isochron map in the neighborhood of this periodic solution.
