In a written correspondence with A. Livingston, Erdős conjectured that for any arithmetical function f , periodic with period q, taking values in {−1, 1} when q ∤ n and f (n) = 0 when q n, the series ∑ ∞ n=1 f (n) n does not vanish. This conjecture is still open in the case q ≡ 1 mod 4 or when 2φ(q) + 1 ≤ q. In this paper, we obtain the characteristic function of the limiting distribution of L(k, f ) for any positive integer k and Erdős function f with the same parity as k. Moreover, we show that the Erdős conjecture is true with "probability" one.2010 Mathematics Subject Classification. 11M99.
