Cauchy-Riemann equations [kō·shē ′rē‚män i′kwā·zhənz]

(mathematics)

A pair of partial differential equations that is satisfied by the real and imaginary parts of a complex function ƒ(z) if and only if the function is analytic: ∂u/∂x= ∂v/∂yand ∂u/∂y= - ∂v/∂x,where ƒ(z) =u+ivandz=x+iy.

Cauchy-Riemann Equations

in the theory of analytic functions, partial differential equations of the first order connecting the real and imaginary parts of an analytic function w = u + iv of the complex variable z = x + iy:

∂u/∂x = ∂v/∂y ∂u/∂y = −∂v/∂x

These equations are of fundamental importance in the theory of analytic functions and in its applications to mechanics and physics. They were first examined by J. d'Alembert and L. Euler long before the works of A. Cauchy and B. Riemann.
