ComplexBranchDerivative

$$f'(z)$$

Complex derivative, allowing branch cuts. This operator is equivalent to ComplexDerivative, except that whereas ComplexDerivative is undefined on a branch cut (where the function is not complex differentiable), ComplexBranchDerivative gives the complex derivative of the analytically continued function across the branch cut.
