Singular perturbations arising in complex Newton's method

Singular perturbations arising in complex Newton's method

We examine the resulting dynamics when Newton's method is applied to perturbations on polynomials that have a multiple root. Specifically, we consider the case where Newton's method is applied to the polynomial family $(z^2 + c)(z-1).$
