    Bounding zeta on the 1-line under the partial Riemann hypothesis
    (Cambridge University Press, 2024-10-01)
    We provide explicit bounds for the Riemann zeta-function on the line, assuming that the Riemann hypothesis holds up to height T. In particular, we improve some bounds in finite regions for the logarithmic derivative and the reciprocal of the Riemann zeta-function.

    Explicit conditional bounds for $\zeta(s)$ at the edge of the critical strip
    (European Mathematical Society, 2026-06-19)
    In this paper, we obtain explicit bounds for the real part of the logarithmic derivative of the Riemann zeta-function on the line \operatorname{Re}s=1 , assuming the Riemann hypothesis. The proof combines the Guinand–Weil explicit formula with extremal bandlimited majorants and minorants for the Poisson kernel. As an application, we revisit the classical estimates of Littlewood for the modulus of the Riemann zeta-function and of its reciprocal on the line \operatorname{Re}{s}=1 , and derive a slight refinement of the bounds of Lamzouri, Li, and Soundararajan. In addition, we establish an explicit bound for the modulus of the logarithmic derivative of the Riemann zeta-function on the line \operatorname{Re}{s}=1 under the Riemann hypothesis, improving the lower-order term in a result of Chirre, Hagen, and Simonič.

    Explicit conditional bounds for $ζ(s)$ at the edge of the critical strip
    (Cornell University, 2026-02-05)
    In this paper, we obtain explicit bounds for the real part of the logarithmic derivative of the Riemann zeta-function on the line $\re s=1$, assuming the Riemann hypothesis. The proof combines the Guinand--Weil explicit formula with extremal bandlimited majorants and minorants for the Poisson kernel. As an application, we revisit the classical estimates of Littlewood for the modulus of the Riemann zeta-function and of its reciprocal on the line $\re{s}=1$, and derive a slight refinement of the bounds of Lamzouri, Li, and Soundararajan. In addition, we establish an explicit bound for the modulus of the logarithmic derivative of the Riemann zeta-function on the line $\re{s}=1$ under the Riemann hypothesis, improving the lower-order term in a result of Chirre, Valås, and Simonič.
