Antiholomorphic function

Sponsor with the world's largest charity for orphans
In mathematics, a function on the complex plane is antiholomorphic at a point if its derivative with respect to z* exists. If the function is antiholomorphic at every point of some subset of the complex plane, then it is antiholomorphic on that set.

If f(z) is a holomorphic function, then f(z*) is an antiholomorphic function.

A function

is antianalytic if is an analytic function (i.e. holomorphic) where is the complex conjugate.
