### Abstract

The indicator function of the set of k-th power free integers is naturally extended to a random variable X^{(k)}({dot operator}) on (ℤ○,λ), where ℤ○ is the ring of finite integral adeles and λ is the Haar probability measure. In the previous paper, the first author noted the strong law of large numbers for {X^{(k)}({dot operator}+n)}^{∞}
_{n=1}, and showed the asymptotics: E^{λ}[(Y^{(k)}
_{N})^{2}]{equivalent to}1 as N→∞, where Y^{(k)}
_{N}(x):=N^{-1/2k}∑^{N}
_{n=1}(X(k)(x+n)-1/ζ(k)). In the present paper, we prove the convergence of E^{λ}[(Y^{(k)}
_{N})^{2}]. For this, we present a general proposition of analytic number theory, and give a proof to this.

In the previous paper, the first author noted the strong law of large numbers for {X(k)({dot operator}+n)}∞ n=1, and showed the asymptotics: Eλ[(Y(k) N)2]{equivalent to}1 as N→∞, where Y(k) N(x):=N-1/2k∑N n=1(X(k)(x+n)-1/ζ(k)). In the present paper, we prove the convergence of Eλ[(Y(k) N)2]. For this, we present a general proposition of analytic number theory, and give a proof to this.
