Let Λ (n) be the arithmetic function usually so denoted, which is zero unless n is a prime power pm (m ≥ 1), when it is log p. We write as usual
and
where the dash denotes that if x is an integer the last term Λ (x) of the sum is to be taken with a factor ½. We wrute further

‡ Our convention as to the use of O implies, of course, that the formula holds “uniformly for y ≥ √x.”
* I hope to publish this result shortly in another paper.
* Since all roots with γ > 0 lie in 0 < σ < 1, and are symmetrically disposed about the line σ = frac12;
† s 0 is a pure imaginary, and s describes the real axis as ζ describes the large rectangle.
* Here and in the argument below we use the inequality
A glance at the inequalities immediately following verifies the condition |z| < ½.
* Γ4 extends to the left (only) as far as σ = − 19.
† We naturally choose the determination of log ζ defined by the Dirichlet series for σ > 1.
