Dear all,
There is a complex dynamics seminar today. Details follow.
Matthieu Arfeux (Université de Toulouse)
'Deligne-Mumford compactification and Berkovich spaces'
Thursday 1 May, 4pm in room 306 Alan Turing Building
Tea and coffee served at 3.30pm in the common area
Abstract: The space of rational map of degree d>1 modulo conjugacy by Moebius transformations is not compact. When you consider a diverging sequence, we can see some phenomena called "rescaling limits". During this talk, I will present and compare two ways to study these phenomena. The first way uses the Deligne-Mumford compactification of the moduli space of marked spheres (my thesis work). The second way uses non-archimedian tools, the Berkovich spaces. I will not expect people to know anything about these two topics.
Best wishes,
Ian
