*an*satisfies the second form of condition (i), the series*f(y)*is necessarily convergent (absolutely) for*y*>0, so that the first clause of condition (ii) is tnen unnecessary. There are more general forms of this theorem, involving functions such as\(y^{ - a} \left\{ {\log \left( {\frac{1}{y}} \right)} \right\}^{a_1 } \left\{ {\log \log \left( {\frac{1}{y}} \right)} \right\}^{a_2 } \cdots \cdots .,\) which we have not troubled to work out in detail. The relation*f(y)*∼*Ay*^{−a}in condition (ii) must be interpreted, in the special case when*A=0*, as meaning*f(y)=0(y-a)*; and a corresponding change must be made in the conclusion.Google Scholar - 1.The argument is so much like that ofLandau (
*Prace Matematyczno-Fizyczne*, vol. 21, pp. 173*et seq.*) that it is hardly worth while to set it out in detail. We applyCauchy's Theorem to the rectangle\(c - iT,x - iT,x + iT,c - iT,\) and then suppose that*T*→∞.Google Scholar - 1.

- 1.The passage from (2. 211) to (2. 212) requires in reality a difficult and delicate discussion. If we suppress this part of the proof, it is because no arguments are required which involve the slightest novelty of idea. All the materials for the proof are to be found inLandau's
*Handbuch*(pp. 333–368). But the problem treated there is considerably more difficult than this one, inasmuch as the integrals and series dealt with are not absolutely convergent. Here everything is absolutely convergent, since |Γ(σ+*ti*)*y*^{σ+ti}|, where ℜ(ity)>o, tends to zero like an exponential when*t*→∞.Google Scholar - 1.

*y*) is a power-series convergent for |*y*|<*2*π, is of course evident.Google Scholar - 1.

*Acta mathematica*, vol. 40, 1916, pp. 185–190. The actual formula communicated to us byRiesz (in 1912) was not this one, nor the formula for\(\frac{I}{{\zeta \left( s \right)}}\), contained in his memoir, but the analgogous formula for\(\frac{I}{{\zeta \left( {s + I} \right)}}\). All of these formulae may be deduced from*Mellin's*inversion formula already referred to in 2.53. The idea of obtaining a necessary and sufficient condition of this character for the truth of theRiemann hypothesis is of courseRiesz's and not ours.CrossRefGoogle Scholar - 2.Comptes Rendus, 29 Jan. 1912.Google Scholar
