Brolin’s equidistribution theorem in $$p$$-adic dynamics. (Théorème d’équidistribution de Brolin en dynamique $$p$$-adique.) (French. Abridged English version) Zbl 1052.37039
Summary: We prove an analog of the famous equidistribution theorem of Brolin for rational mappings in one variable defined over the $$p$$-adic field $$\mathbb{C}_p$$. We construct a mixing invariant probability measure which describes the asymptotic distribution of iterated preimages of a given point. This measure is supported on the Berkovich space $$P^1(\mathbb{C}_p)$$ associated to $$\mathbb{P}^1 (\mathbb{C}_p)$$. We show that its support is precisely the Julia set of $$R$$ as defined by Rivera-Letelier. Our results are based on the construction of a Laplace operator on real trees with arbitrary number of branching as done in [C. Favre and M. Jonsson, The valuative tree, Lecture Notes in Mathmatics. Berlin etc.: Springer-Verlag, in press].
