The main result is an upper bound for the Riemann zeta function in the critical strip: ζ(σ+it)⩽A|t|B(1−σ)3/2log2/3⁡|t| with A = 76.2 and B = 4.45, valid for ½ ⩽ σ ⩽ 1 and |t| ⩾ 3. The previous best constant B was 18.5. Tools include a variant of the Korobov–Vinogradov method of bounding exponential sums, an explicit version of T. D. Wooley's bounds for Vinogradov's integral, and explicit bounds for mean values of exponential sums over numbers without small prime factors, also using methods of…

Abstract. In 2005 Kadiri proved that the Riemann zeta function ζ(s)does not vanish in the regionRe(s) ≥ 1 −1R 0 log|Im(s)|, |Im(s)| ≥ 2with R 0 = 5.69693. In this paper we will show that R 0 can be

Thanks to Littlewood (1922) and Ingham (1928), we know the ﬁrst two terms of the asymptotic formula for the square mean integral value of the Riemann zeta function ζ on the critical line. Later,
Zero-free regions for the Riemann zeta function
We improve existing explicit bounds of Vinogradov-Korobov type for zero-free regions of the Riemann zeta function, both for large height t and for every t. A primary input is an explicit bound of the

Bounds on the tails of the zeta function ζ(s), and in particular explicit bounds, are needed for applications, notably for integrals involving ζ(s) on vertical lines or other paths going to infinity.
Bounds on short character sums and L-functions with characters to a powerful modulus
• Mathematics
Journal d'Analyse Mathématique

We combine a classical idea of Postnikov (1956) with the method of Korobov (1974) for estimating double Weyl sums, deriving new bounds on short character sums when the modulus q has a small core
A new kth derivative estimate for exponential sums via Vinogradov’s mean value
We give a slight refinement to the process by which estimates for exponential sums are extracted from bounds for Vinogradov’s mean value. Coupling this with the recent works of Wooley, and of
Explicit bounds on the logarithmic derivative and the reciprocal of the Riemann zeta-function
: The purpose of this article is consider | ζ (cid:48) ( σ + it ) /ζ ( σ + it ) | and | ζ ( σ + it ) | − 1 when σ is close to unity. We prove that | ζ (cid:48) ( σ + it ) /ζ ( σ + it ) | (cid:54)
Explicit $L^2$ bounds for the Riemann $\zeta$ function
• Mathematics, Computer Science
• 2019
Bounds on the tails of the zeta function $\zeta(s)', inspired by the standard mean value theorem for Dirichlet polynomials, are presented, giving main terms of the correct order for$0<\sigma\leq 1\$ and are strong enough to be of practical use in giving precise values for integrals when combined with (rigorous) numerical integration.
