摘要

S(t)=1πlogζ(12+it)S(t) = \frac{1}{\pi}\Im \log\zeta\left(\frac{1}{2}+it\right)。我们对集合{t[T,2T] ⁣:S(t)V}\{t\in [T,2T] \colon S(t) \geq V\}的测度证明了无条件下界,其中loglogTV(logTloglogT)1/3\sqrt{\log\log T} \leq V \ll \left(\frac{\log T}{\log \log T}\right)^{1/3}。当V(logT)1/3εV \leq (\log T)^{1/3-\varepsilon}时,我们的界呈高斯形状,方差正比于loglogT\log\log T。在端点V(logTloglogT)1/3V \asymp \left(\frac{\log T}{\log \log T}\right)^{1/3}处,我们的结果蕴含了Tsang所给出的关于S(t)S(t)的最佳已知Ω\Omega定理。我们还解释了基于当前对zeta函数零点的认知,当V(logTloglogT)1/3V \gg \left(\frac{\log T}{\log \log T}\right)^{1/3}时该方法为何失效。在黎曼假设条件下,我们将结果推广至loglogTV(logTloglogT)1/2\sqrt{\log\log T} \leq V \ll \left(\frac{\log T}{\log \log T}\right)^{1/2}的范围。
