Abstract

TextLet K be a complete, algebraically closed, non-Archimedean valued field, and let ϕ∈K(z) with deg⁡(ϕ)≥2. In this paper we consider the family of functions ordResϕn(x), which measure the resultant of ϕn at points x in PK1, the Berkovich projective line, and show that they converge locally uniformly to the diagonal values of the Arakelov–Green's function gμϕ(x,x) attached to the canonical measure of ϕ. Following this, we are able to prove an equidistribution result for Rumely's crucial measures νϕn, each of which is a probability measure supported at finitely many points whose weights are determined by dynamical properties of ϕ.
