高阶Poisson型非线性系统解的存在性

On the existence of solutions to nonlinear systems of higher order Poisson type

Yifei Pan, Yuan Zhang

摘要:

本文研究了高阶Poisson型系统解的存在性。详细地证明了$\RR^n, n\ge 3$中Laplacian基本解的留数型现象。这类似于$\CC$中柯西核的留数定理。借助于基本解的留数型公式,我们导出了牛顿位势的高阶导数公式,并得到了它的适当的$\s C^{k, α}$估计.作为不动点定理的一个应用,得到了高阶Poisson型非线性系统解的存在性.

英文摘要:

In this paper, we study the existence of higher order Poisson type systems. In detail, we prove a Residue type phenomenon for the fundamental solution of Laplacian in $\RR^n, n\ge 3$. This is analogous to the Residue theorem for the Cauchy kernel in $\CC$. With the aid of the Residue type formula for the fundamental solution, we derive the higher order derivative formula for the Newtonian potential and obtain its appropriate $\s C^{k, α}$ estimates. The existence of solutions to higher order Poisson type nonlinear systems is concluded as an application of the fixed point theorem.
