Theorem A. Let q >/= O and r >/= O be integers. Let s = sigma + it, let zeta(s) be the Riemann zeta-function, let G(o)(s) = 1, and [Formula: see text] and let F(s) = G(q)(s)/H(r)(s). Then as t --> infinity lim sup [unk]F(1 + it)[unk]/(log log t)(q+r+1) >/= (6/pi)(2))(r+1) exp {(q + r + 1)gamma}, where gamma is Euler's constant.Stronger results such as proved in [1] are valid, and in particular q and r can be allowed to increase with t as in [1]. Results involving the real part of the sum of the factors of G(q) and of the reciprocals of the factors of H(r) can be proved much as in [3].
定理A。设q≥0且r≥0为整数。设s = σ + it,ζ(s)为黎曼ζ函数,设G(0)(s) = 1,且[公式:见文本],并设F(s) = G(q)(s)/H(r)(s)。那么当t→∞时,lim sup |F(1 + it)|/(log log t)(q + r + 1)≥(6/π)(2)(r + 1) exp{(q + r + 1)γ},其中γ为欧拉常数。[1]中证明的更强结果是有效的,特别地,q和r可以像[1]中那样随t增大。涉及G(q)的因子之和的实部以及H(r)的因子的倒数之和的实部的结果,证明方式与[3]中大致相同。
