关于$ζ(1/2+it)$的矩中矩

On the moments of the moments of $ζ(1/2+it)$

E. C. Bailey, J. P. Keating

摘要:

从$[0,T]$随机均匀地取$t$,我们考虑在区间$x\in(t, t+1]$上对应于$ζ(1/2+ix)$的$2β$阶矩的随机变量关于$t$的$k$阶矩,其中$ζ(s)$是Riemann zeta函数。我们称之为“时刻的时刻”的黎曼zeta函数,并提出了一个猜想,他们的渐近性,当$T\to\infty$,为整数$k,β$。这是出于随机酉矩阵的特征多项式的时刻的结果的比较,并示出遵循从一个猜想的$ζ(s)$由于康利,农民,基廷,鲁宾斯坦,和Snaith \cite{cfkrs2}的移动时刻。具体来说,我们证明了一个功能,转移的时刻猜想的\cite{cfkrs2}意味着,是一个密切的近似时刻的zeta函数的时刻满足渐近公式,我们猜想。我们激励以及类似的aceturtures的时刻,时刻为其他家庭的原始$L$ -功能。

英文摘要:

Taking $t$ at random, uniformly from $[0,T]$, we consider the $k$th moment, with respect to $t$, of the random variable corresponding to the $2β$th moment of $ζ(1/2+ix)$ over the interval $x\in(t, t+1]$, where $ζ(s)$ is the Riemann zeta function. We call these the `moments of moments' of the Riemann zeta function, and present a conjecture for their asymptotics, when $T\to\infty$, for integer $k,β$. This is motivated by comparisons with results for the moments of moments of the characteristic polynomials of random unitary matrices and is shown to follow from a conjecture for the shifted moments of $ζ(s)$ due to Conrey, Farmer, Keating, Rubinstein, and Snaith \cite{cfkrs2}. Specifically, we prove that a function which, the shifted-moment conjecture of \cite{cfkrs2} implies, is a close approximation to the moments of moments of the zeta function does satisfy the asymptotic formula that we conjecture. We motivate as well similar conjectures for the moments of moments for other families of primitive $L$-functions.
