Abstract:

In this talk we will present a family of rational maps obtained by applying the Chebyshev-Halley family of root-finding algorithms to $z^3-1$. We will show that, for certain parameters, these maps can be studied from the point of view of singular perturbations. We will also show that, for such parameters, the corresponding Julia sets can be locally connected and contain Cantor sets of quasicircles.
