Abstract

Let 1/2β<11/2\leq\beta<1, pp be a generic prime number and fβf_\beta be a random multiplicative function supported on the squarefree integers such that (fβ(p))p(f_\beta(p))_{p} is an i.i.d. sequence of random variables with distribution P(f(p)=1)=β=1P(f(p)=+1)\mathbb{P}(f(p)=-1)=\beta=1-\mathbb{P}(f(p)=+1). Let FβF_\beta be the Dirichlet series of fβf_\beta. We prove a formula involving measure-preserving transformations that relates the Riemann ζ\zeta function with the Dirichlet series of FβF_\beta, for certain values of β\beta, and give an application. Further, we prove that the Riemann hypothesis is connected with the mean behavior of a certain weighted partial sums of fβf_\beta.
