具有非局部、非势漂移的非线性扩散问题的分裂方法

A splitting method for nonlinear diffusions with nonlocal, nonpotential drifts

Guillaume Carlier, Maxime Laborde

摘要:

证明了非线性扩散方程在非局部密度依赖漂移不一定是势的情况下解的存在性结果。证明是建设性的,并基于亥姆霍兹分解的漂移和分裂计划。分裂方案结合了漂移的无发散部分的传输步骤和半隐式最小化步骤来处理势部分。

英文摘要:

We prove an existence result for nonlinear diffusion equations in the presence of a nonlocal density-dependent drift which is not necessarily potential. The proof is constructive and based on the Helmholtz decomposition of the drift and a splitting scheme. The splitting scheme combines transport steps by the divergence-free part of the drift and semi-implicit minimization steps à la Jordan-Kinderlherer-Otto to deal with the potential part.
