AI 中文摘要
针对一类概率密度的非线性Fokker-Planck方程,我们通过使用球内非线性Neumann问题的逼近格式构造了分布解。此外,我们引入了非线性泛函不等式来估计分布解向平稳解的收敛速率,关于p-方差(p∈[1,2]),包括相对熵(p=1)和方差(p=2)。这些非线性泛函不等式随后在非退化和退化情形下均被建立,使得主要结果可应用于多种具有不同收敛速率的典型模型。
英文摘要
For a class of nonlinear Fokker-Planck equations for probability densities, we construct distributional solutions by using an approximation scheme with nonlinear Neumann problems in balls. Moreover, we introduce nonlinear functional inequalities to estimate the convergence rates of the distributional solutions to the stationary solution, with respect to the $p$-variance for $p\in [1,2]$ including the relative entropy $(p=1)$ and the variance $(p=2)$. These nonlinear functional inequalities are then established in both non-degenerate and degenerate settings, so that the main results are applied to a number of typical models with various convergence rates.
