A new upper bound on the smallest counterexample to the Mertens conjecture (2305.00345v1)
Published 29 Apr 2023 in math.NT
Abstract: We report the finding of the new upper bound on the lowest positive integer $x$ for which the Mertens conjecture \begin{equation*} \left| \sum_{1 \leq n \leq x} \mu(n) \right| < \sqrt{x} \end{equation*} fails to hold: $x < \exp(1.017 \times 10{29})$, an improvement over previously known $\exp(1.59 \times 10{40})$ due to Kotnik and te Riele [7].
