Cauchy-Riemann equation
- (mathematics, complex analysis, always plural) Given a complex-valued function f and real-valued functions u and v such that f(z) = u(z) + iv(z), either of the equations \textstyle \frac{\partial u}{\partial x} = \frac{\partial v}{\partial y} or \textstyle \frac{\partial u}{\partial y} = -\frac{\partial v}{\partial x}, which together form part of the criteria that f be complex-differentiable.
- (complex analysis) The equivalent single equation \textstyle \frac{\partial f}{\partial x} + i\frac{\partial f}{\partial y} = 0.
