Abstract

Let Λ\Lambda be a quasi-projective variety and assume that, either Λ\Lambda is a subvariety of the moduli space Md\mathcal{M}_d of degree dd rational maps, or Λ\Lambda parametrizes an algebraic family (fλ)λΛ(f_\lambda)_{\lambda\in\Lambda} of degree dd rational maps on P1\mathbb{P}^1. We prove the equidistribution of parameters having pp distinct neutral cycles towards the pp-th bifurcation current letting the periods of the cycles go to \infty, with an exponential speed of convergence. We deduce several fundamental consequences of this result on equidistribution and counting of hyperbolic components. A key step of the proof is a locally uniform version of the quantitative approximation of the Lyapunov exponent of a rational map by the log+\log^+ of the modulus of the multipliers of periodic points.
