Fokker-Planck方程稳定性的定量估计

Quantitative stability estimates for Fokker-Planck equations

Huaiqian Li, Dejun Luo

摘要:

本文研究具有非正则系数的Fokker-Planck方程。两种不同的情况下处理:在退化的情况下,系数被假定为弱可微,而在非退化的情况下,漂移只满足Ladyzhenskaya-Prodi-Serrin条件。利用将解表示为扩散算子的鞅问题解的边缘的Trevisan叠加原理,建立了Fokker-Planck方程解的定量稳定性估计.

英文摘要:

We consider the Fokker--Planck equations with irregular coefficients. Two different cases are treated: in the degenerate case, the coefficients are assumed to be weakly differentiable, while in the non-degenerate case the drift satisfies only the Ladyzhenskaya--Prodi--Serrin condition. Using Trevisan's superposition principle which represents the solution as the marginal of the solution to the martingale problem of the diffusion operator, we establish quantitative stability estimates for the solutions of Fokker--Planck equations.
