Abstract
We consider a systematic generalization of the well-known cube roots of -1 problem to include the Nth roots. The associated fractal basin boundaries are computed, and we also explore how sensitive this class of systems is to fluctuations at its input by estimating the “uncertainty” fractal dimension. Other curious results are uncovered along the way.
