一类非线性迁移方程的适定性

$C^γ$ well-posedness of some non-linear transport equations

J. C. Cantero

摘要:

给定$k:\mathbb{R}^n\setminus\{0\} \to \mathbb{R}^n$是$C^2$类的核和$1-n$的齐次函数,我们证明了一类速度场由密度与$k$的卷积给出的非线性迁移方程的Hölder正则解的存在唯一性.对于$k$的特定选择,可以恢复聚合、三维准地转和二维欧拉方程。

英文摘要:

Given $k:\mathbb{R}^n\setminus\{0\} \to \mathbb{R}^n$ a kernel of class $C^2$ and homogeneous of degree $1-n$, we prove existence and uniqueness of Hölder regular solutions for some non-linear transport equations with velocity fields given by convolution of the density with $k$. The Aggregation, the 3D quasi geostrophic, and the 2D Euler equations can be recovered for particular choices of $k$.
