这节的目的是 Cauchy–Riemann 方程. 注意, 我们是在不涉及导数, 解析函数的前提下做这件事.

Cauchy–Riemann 方程

大名鼎鼎的 Cauchy–Riemann equations:

\[\begin{cases}\frac{\partial u}{\partial x}=\frac{\partial v}{\partial y};\\ \frac{\partial u}{\partial y}=-\frac{\partial v}{\partial x}.\end{cases}\]

这是一个偏微分方程组, 是复分析的核心.

Cauchy–Riemann equations 与 Maxwell’s equations

Cauchy–Riemann equations 与 Maxwell’s equations 是有联系的.
