摘要：

We derive quantitative stability estimates for solutions of Fokker-Planck equations with irregular coefficients. We are mainly concerned with two different situations: in the degenerate case, the coefficients are assumed to be weakly differentiable, while in the non-degenerate case the drift coefficient satisfies only the Ladyzhenskaya- Prodi-Serrin condition. Our method is based on Trevisan's superposition principle, which represents the solution to the Fokker-Planck equation as the marginal distribution of the martingale solution of the associated stochastic differential equation.
