The Uniform Distribution Modulo One of Certain Subsequences of Ordinates of Zeros of the Zeta Function

Fatma Çiçek, Steven M. Gonek

On the assumption of the Riemann hypothesis and a spacing hypothesis for the nontrivial zeros $\frac{1}{2} + iγ$ of the Riemann zeta function, we show that the sequence \[ Γ_{[a, b]} =\B…
