Definition:Primitive (Calculus)/Complex

Definition
Let $F: D \to \C$ be a complex function which is complex-differentiable on a connected domain $D$.

Let $f: D \to \C$ be a continuous complex function.

Let:
 * $\forall z \in D: F' \left({z}\right) = f \left({z}\right)$

where $F'$ denotes the derivative of $F$.

Then $F$ is a primitive of $f$.

A primitive is also known as an antiderivative.
