题 目：Deligne-Mumford compactification and dynamics on Berkovich spaces
摘 要：In this talk we will take time to introduce and compare two different languages developed these last years to talk about an interesting problem in holomorphic dynamics: existence of rescaling limits. The non experts are more than welcome as the talk will not require any knowledge on holomorphic dynamics or algebraic geometry. More in details, we will see that the Deligne-Mumford compactification of the moduli space of the punctured sphere is naturally contained in the Berkovich projective line over the field of formal Puiseux series.
