Théorème d’Erdős–Kac dans presque tous les petits intervalles

Volume 182 / 2018

Élie Goudout Acta Arithmetica 182 (2018), 101-116 MSC: Primary 11N25. DOI: 10.4064/aa8480-11-2017 Published online: 11 January 2018

Abstract

We show that the Erdős–Kac theorem is valid in almost all intervals $[x,x+h]$ as $h$ tends to infinity with $x$. We also show that for all $k$ near $\log\log x$, almost all intervals $[x,x+\exp((\log\log x)^{1/2+\varepsilon})]$ contain the expected number of integers $n$ such that $\omega(n)=k$. These results are a consequence of the methods introduced by Matomäki and Radziwiłł to estimate sums of multiplicative functions over short intervals.
