Truncated pretentious distances of multiplicative arithmetic functions
Abstract
Let f:ℕ→𝕌 be a non-pretentious multiplicative function in the sense of Granville and Soundararajan. We study the convergence of the autocorrelation averages of f. In particular, we investigate the relationship between the local pretentious behaviour of f on intervals of the form [xε,x] and its deviation from $1$ on the primes. As an application, we exhibit a class of non-pretentious multiplicative functions for which Elliott's conjecture in its original formulation holds, following up on a result by Klurman, Mangerel and Teräväinen.
