Book DetailsGraduate Studies in MathematicsVolume: 198; 2019; 463 ppMSC: Primary 37;
The theory of complex dynamics in one variable, initiated by Fatou and Julia in the early twentieth century, concerns the iteration of a rational function acting on the Riemann sphere. Building on foundational investigations of \(p\)adic dynamics in the late twentieth century, dynamics in one nonarchimedean variable is the analogous theory over nonarchimedean fields rather than over the complex numbers. It is also an essential component of the numbertheoretic study of arithmetic dynamics.
This textbook presents the fundamentals of nonarchimedean dynamics, including a unified exposition of RiveraLetelier's classification theorem, as well as results on wandering domains, repelling periodic points, and equilibrium measures. The Berkovich projective line, which is the appropriate setting for the associated Fatou and Julia sets, is developed from the ground up, as are relevant results in nonarchimedean analysis. The presentation is accessible to graduate students with only firstyear courses in algebra and analysis under their belts, although some previous exposure to nonarchimedean fields, such as the \(p\)adic numbers, is recommended. The book should also be a useful reference for more advanced students and researchers in arithmetic and nonarchimedean dynamics.ReadershipGraduate students and researchers interested in arithmetic and nonarchimedean dynamics.

This book would be good for a topics course in Berkovich space for a graduate student familiar with real and complex analysis. [Bennedeto] makes Berkovich space accessible to the new researcher.
