Abstract

Given a ±1 random completely multiplicative function f, we prove by estimating moments that the limiting distribution of the normalized sumconverges to the standard Gaussian distribution as x → ∞ when r restricts summation to n having o(log log log x) prime factors. We also give an upper bound for the large deviations ofwith the sum restricted to numbers having a fixed number k of prime factors.
