关于无理奇ζ值个数的注记

数论 2020-10-14 v2

摘要

证明了对于所有奇整数ss0(ε)s \geqslant s_0(\varepsilon),在如下奇ζ值:ζ(3),ζ(5),ζ(7),,ζ(s)\zeta(3),\zeta(5),\zeta(7),\cdots,\zeta(s)中,至少有(c0ε)s1/2(logs)1/2\big( c_0 - \varepsilon \big) \frac{s^{1/2}}{(\log s)^{1/2}}个无理数。常数c0=1.192507c_0 = 1.192507\ldots可以闭式表达。该工作基于Fischler、Sprang与Zudilin [FSZ19]的先前工作,改进了其中的下界2(1ε)logsloglogs2^{(1-\varepsilon)\frac{\log s}{\log\log s}}。主要的新要素是辅助有理函数零点的最优设计,其关联到欧拉 totient 函数的逆。
