complex-differentiable (not comparable)

  1. (mathematics, complex analysis, of a function) That is differentiable and satisfies the Cauchy-Riemann equations on a subset of the complex plane.

      This gives the possibility to extend the well-established theory of complex-differentiable operators, a theory with meany[sic] deep results.

      Further it can be shown that the holomorphic function also has a convergent Taylor series, that is, a complex differentiable function is also an analytic function (Section 23.7).
    • 2010, Peter J. Schreier, Louis L. Scharf, Statistical Signal Processing of Complex-Valued Data, Cambridge University Press, page 277 ↗,
      We can of course regard a function f defined on \mathbb{R}^{2n} as a function defined on \mathbb{C}^{n}. If f is differentiable on \mathbb{R}^{2n}, it is said to be real-differentiable, and if f is differentiable on \mathbb{C}^{n}, it is complex-differentiable. A function is complex-differentiable if and only if it is real-differentiable and the Cauchy-Riemann equations hold.
