Let $\\widehat{h}_{\\varphi}$ be the canonical height associated to $\\varphi$ on $X(\\overline{K})$. Given a generic sequence of points $(x_n)$ with $\\widehat{h}_{\\varphi}(x_n) \\to 0$ and a place $v \\in M_K$, Yuan [Yua08] has shown that the conjugates of $x_n$ equidistribute to the canonical measure $\\mu_{\\varphi,v}$. When $v$ is archimedean, we will prove a quantitative version of Yuan's result. We give two applications of our result to polarized endomorphisms $\\varphi$ of smooth projective surfaces that are defined over a number field $K$. The first is an exponential rate of convergence for periodic points of period $n$ to the equilibrium measure and the second is an exponential lower bound on the degree of the extension containing all periodic points of period $n$. When $X$ is an abelian variety, we also give an upper bound on the smallest degree of a hypersurface that contains all points $x \\in X(\\overline{K})$ satisfying $[K(x):K] \\leq D$ and $\\widehat{h}_X(x) \\leq \\frac{c}{D^8}$ for some fixed constant $c > 0$ where $\\widehat{h}_X$ is the Neron--Tate height for $X$.", "revisions": [ { "version": "v1", "updated": "2024-10-29T03:00:47.000Z" } ], "analyses": { "keywords": [ "canonical height", "small points", "quantitative equidistribution", "number field", "periodic points" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
