非线性偏微分方程 - 维基百科，自由的百科全书

非线性偏微分方程是具有非线性项的偏微分方程。起源於各種應用科學中，如固體力學、流體力學、聲學、非線性光學、等離子體物理學、量子場論等學科。它们描述了许多不同的物理系统，并被用于解决数学问题，如庞加莱猜想和卡拉比猜想。它们很难研究：几乎没有通用的技术可以用于所有这样的方程，通常每个单独的方程都必须作为一个单独的问题进行研究。通常，线性和非线性偏微分方程的区别是基于定义偏微分方程本身的算子的属性。

函數關係 F(,x_1,X_2..x_n,u,u_x1,u_x2..u_xn,u_x1x2,u_x1x3...)=0 是一個廣義的偏微分方程，如果 u，v 是此微分方程的兩個解，而（au+bv) 也是此微分方程的解，則此偏微分方程稱為線性偏微分方程，否則稱為非線性偏微分方程。^[1]
