The Uniform Distribution Modulo One of Certain Subsequences of Ordinates of Zeros of the Zeta Function (2310.10119v1)

Abstract: On the assumption of the Riemann hypothesis and a spacing hypothesis for the nontrivial zeros $\frac12+i\gamma$ of the Riemann zeta function, we show that the sequence [ \Gamma_{[a, b]} =\Bigg{ \gamma : \gamma>0 \quad \mbox{and} \quad \frac{ \log\big(| \zeta^{(m_{\gamma})} (\frac12+ i\gamma) | / (\log{\gamma})^{m_{\gamma}}\big)}{\sqrt{\frac12\log\log{\gamma}}} \in [a, b] \Bigg}, ] where the $\gamma$ are arranged in increasing order, is uniformly distributed modulo one. Here $a$ and $b$ are real numbers with $a<b$, and $m_{\gamma}$ denotes the multiplicity of the zero $\frac12+i\gamma$. The same result holds when the $\gamma$'s are restricted to be the ordinates of simple zeros. With an extra hypothesis, we are also able to show an equidistribution result for the scaled numbers $\gamma (\log T)/2\pi$ with $\gamma\in \Gamma_{[a, b]}$ and $0<\gamma\leq T$.
