Quadratic rational maps with a $2$-cycle of Siegel disks

Dynamical Systems 2022-06-30 v2 Complex Variables

Abstract

For the family of quadratic rational functions having a 22-cycle of bounded type Siegel disks, we prove that each of the boundaries of these Siegel disks contains at most one critical point. In the parameter plane, we prove that the locus for which the boundaries of the 22-cycle of Siegel disks contain two critical points is a Jordan curve.
