Rational maps with bad reduction and domains of quasiperiodicity

Abstract

Consider a rational map $R$ of degree $d\ge 2$ with coefficients over the non-archimedean field ${\mathbb{C}}_p$, with $p$ a fixed prime number. If $R$ has a cycle of Siegel disks and has good reduction, then it was shown by Rivera-Letelier in his PhD dissertation that a new rational map $Q$ can be constructed from $R$, in such a way that $Q$ will exhibit a cycle of $m$-Herman rings. In this paper, we address the case of rational maps with bad reduction and provide an extension of Rivera-Letelier's result for these class of maps.
