We establish a relation between the lower bound for the maximum of the modulus of $\zeta (1/2 + iT + s)$ in the disk $|s| \leqslant H$ and the lower bound for the maximum of the modulus of $\zeta (1/2 + iT + it)$ on the closed interval $|t| \leqslant H$ for $0 < H(T) \leqslant {1 \mathord{\left/ {\vphantom {1 2}} \right. \kern-0em} 2}$ . We prove a theorem on the lower bound for the maximum of the modulus of $0 < H(T) \leqslant {1 \mathord{\left/ {\vphantom {1 2}} \right. \kern-0em} 2}$ on the closed interval $|t| \leqslant H$ for $40 \leqslant H(T) \leqslant \log \log T$ . 相似文献

After reviewing properties of analytic functions on the multicomplex number space ${\mathbb{C}_{k}}$ (a commutative generalization of the bicomplex numbers ${\mathbb{C}_{2}}$ ), a multicomplex Riemann zeta function is defined through analytic continuation. Properties of this function are explored, and we are able to state a multicomplex equivalence to the Riemann hypothesis. 相似文献

Let $ζ(s)$ be the Riemann zeta function, $s=\sigma+it$. For $0 < \sigma < 1$, we expand $ζ(s)$ as the following series convergent in the space of slowly increasing distributions
with variable $t$ : $$ζ(\sigma+it)=\sum\limits^∞_{n=0}a_n(\sigma)ψ_n(t),$$ where $$ψ_n(t)=(2^nn!\sqrt{\pi})^{-1 ⁄ 2}e^{\frac{-t^2}{2}}H_n(t),$$ $H_n(t)$ is the Hermite polynomial, and $$a_n(σ)=2\pi(-1)^{n+1}ψ_n(i(1-σ))+(-i)^n\sqrt{2\pi}\sum\limits^∞_{m=1}\frac{1}{m^σ}ψ_n(1nm).$$ This paper is concerned with the convergence of the above series for $σ > 0.$ In the deduction,
it is crucial to regard the zeta function as Fourier transfomations of Schwartz'
distributions. 相似文献

Let $$F_{a}(s) = \left(1 - 1\frac{1}{\zeta(s)}\right)^{1/(s-a)}(a \leq 1; s > 1),$$ where ?? denotes the Riemann zeta function. We prove: F a is strictly decreasing on (1, ??) if and only if a ?? 0, whereas F a is strictly increasing on (1, ??) if and only if a =?1. In particular, this settles a conjecture of Batir, who claimed that F 0 is strictly monotonic for s >?1. Moreover, we apply the monotonicity theorem to obtain some inequalities involving F a . 相似文献

We prove the leading order of a conjecture by Fyodorov, Hiary, and Keating about the maximum of the Riemann zeta function on random intervals along the critical line. More precisely, as T → ∞ for a set of t ∊ [T, 2T] of measure (1–o(1)) T, we have © 2018 Wiley Periodicals, Inc. 相似文献

A Van der Corput exponential sum is S = exp (2 i f(m)) wherem has size M, the function f(x) has size T and = (log M) / log T < 1. There are different bounds for S in differentranges for . In the middle range where is near 1/over 2, . This bounds the exponent of growthof the Riemann zeta function on its critical line Re s = 1/over2. Van der Corput used an iteration which changed at each step.The BombieriIwaniec method, whilst still based on meansquares, introduces number-theoretic ideas and problems. TheSecond Spacing Problem is to count the number of resonancesbetween short intervals of the sum, when two arcs of the graphof y = f'(x) coincide approximately after an automorphism ofthe integer lattice. In the previous paper in this series [Proc.London Math. Soc. (3) 66 (1993) 140] and the monographArea, lattice points, and exponential sums we saw that coincidenceimplies that there is an integer point close to some resonancecurve, one of a family of curves in some dual space,now calculated accurately in the paper Resonance curvesin the BombieriIwaniec method, which is to appearin Funct. Approx. Comment. Math. We turn the whole BombieriIwaniec method into an axiomatisedstep: an upper bound for the number of integer points closeto a plane curve gives a bound in the Second Spacing Problem,and a small improvement in the bound for S. Ends and cusps ofresonance curves are treated separately. Bounds for sums oftype S lead to bounds for integer points close to curves, andanother branching iteration. Luckily Swinnerton-Dyer's methodis stronger. We improve from 0.156140... in the previous paperand monograph to 0.156098....

通过构造一个Riemann Zeta函数ζ(k)的部分和ζ_n(k)的幂级数函数,利用牛顿二项式展开及柯西乘积公式可以计算出一些重要的和式.再将该幂级数函数由一元推广到二元甚至多元,由此得到Riemann Zeta函数的高次方和式之间的关系.并利用对数函数与第一类Stirling数之间的关系式及ζ(k)函数满足的相关等式,可得出Riemann Zeta函数的18个七阶和式,以及其它一些高次方的和式. 相似文献

利用概率论与组合数学的方法,研究了与Riemann-zeta函数ξ(k)的部分和ξ_n(k)有关的一些级数,计算出了一些重要的和式.特别的,Euler的著名结果5ξ(4)= 2ξ~2(2)能够从四阶和式直接推出.因此,通过计算全部的11个六阶和式,研究它们之间的非平凡关系,就有可能得到ξ(3)的数值. 相似文献

Vinogradov's Integral and Bounds for the Riemann Zeta Function 总被引:2,自引:0,他引:2
The main result is an upper bound for the Riemann zeta functionin the critical strip: with A = 76.2 and B = 4.45, valid for 1 and |t| 3. The previousbest constant B was 18.5. Tools include a variant of the KorobovVinogradovmethod of bounding exponential sums, an explicit version ofT. D. Wooley's bounds for Vinogradov's integral, and explicitbounds for mean values of exponential sums over numbers withoutsmall prime factors, also using methods of Wooley. An auxiliaryresult is the exponential sum bound , where N is a positive integer, t is a real number, = log (t)/(logN) and

我们定义了KS-变换和自然数乘法结构相关的Fourier变换,建立了实数乘法半群[1,∞)={x:x∈R,x≥1}和复半平面Ω={s=σ+it:σ,t∈R,σ≥1/2}之间的由KS-变换诱导的对偶关系,证明了KS-变换是希尔伯特空间L~2([1,∞))和哈代空间H~2(Ω)之间的等距算子,而且该算子保持了相关的函数空间之间由实数的乘法卷积和复数点点相乘诱导出的代数结构的同构.作为应用,我们给出了黎曼假设成立的有关算子指标的等价命题,从而算子理论为研究黎曼ζ-函数和自然数的乘法结构提供了新思路. 相似文献

We slightly improve the lower bound of Báez-Duarte, Balazard, Landreau and Saias in the Nyman-Beurling formulation of the Riemann Hypothesis as an approximation problem. We construct Hilbert space vectors which could prove useful in the context of the so-called “Hilbert-Pólya idea”. 相似文献

A recent paper of Furdui and Vălean proves some results about sums of products of “tails” of the series for the Riemann zeta function. We show how such results can be proved with weaker hypotheses using multiple zeta values, and also show how they can be generalized to products of three or more such tails.
