For polynomial maps in the complex plane, the notion of external rays plays an important role in determining the structure of and the dynamics on the Julia set. In this paper we consider an extension of these rays in the case of rational maps of the form Fλ(z) = zn + λ/zn where n > 1. As in the case of polynomials, there is an immediate basin of ∞, so we have similar external rays. We show...
