The Rate of Convergence for Selberg’s Central Limit Theorem Under the Riemann Hypothesis
摘要
We assume the Riemann hypothesis to improve upon the rate of convergence of \((\log \log \log T)^2/\sqrt{\log \log T}\) in Selberg’s central limit theorem for \(\log |\zeta (1/2+it)|\) given by the author in [8]. We achieve a rate of convergence of \(\sqrt{\log \log \log \log T}/\sqrt{\log \log T}\) in the Dudley distance. The proof is an adaptation of the techniques used by the author in [8], based on the work of Radziwiłł and Soundararajan in [7] and Arguin et al. in [1], combined with a lemma of Selberg [11] that provides for a mollifier close to the critical line \({{\,\textrm{Re}\,}}(s)=1/2\) under the Riemann hypothesis.
