Explicit bounds for the Riemann Zeta function
by
Kevin Ford
University of South Carolina

The Vinogradov-Korobov method of exponential sums produces a bound for the Riemann Zeta function near the line Res = 1 of the form
|\zeta(s+it)| <= A |t|B(1-s)3/2 log2/3 |t|.
We show that one may take B=10.52 and A=100, improving the previous best published bound of B=21. As an application, we show that the zeta function is zero-free in the region
s >= 1 - 0.0044(log|t|)-2/3 (loglog|t|)-1/3, |t| >= 3.
This improves a bound due to Y. Cheng.
