Computational aesthetics for multiple zeros of complex analytic functions
Multiple zeros of complex analytic functions can be localized and counted using certain level curves. This approach provides the setting for a computational-positional system which we have called double newtonization. This process enables the computation of high precision approximations of simple or multiple zeros regardless of their multiplicity.
