摘要:

本文将Conrey,Farmer,Keating,Rubinstein和Snaith等人提出的关于$L$ -函数的积分矩的方法推广到函数域上.我们还适应的功能设置的Conrey,农民和Zirnbauer首次开发的数学研究的平均值的比率的$L$ -功能。具体而言,本文的重点是家庭的二次狄利克雷$L$ -功能$L(s,χ_{P})$的字符$χ$是由勒让德符号定义的多项式在$\mathbb{F}_{q}[T]$与$\mathbb{F}_{q}$一个有限域的奇数基数和平均采取所有monic和不可约多项式$P$的一个给定的奇数程度。作为应用,我们还计算了这些$L$ -函数零点的一级密度公式。

英文摘要:

In this paper we extend to the function field setting the heuristics formerly developed by Conrey, Farmer, Keating, Rubinstein and Snaith, for the integral moments of $L$-functions. We also adapt to the function setting the heuristics first developed by Conrey, Farmer and Zirnbauer to the study of mean values of ratios of $L$-functions. Specifically, the focus of this paper is on the family of quadratic Dirichlet $L$-functions $L(s,χ_{P})$ where the character $χ$ is defined by the Legendre symbol for polynomials in $\mathbb{F}_{q}[T]$ with $\mathbb{F}_{q}$ a finite field of odd cardinality and the averages are taken over all monic and irreducible polynomials $P$ of a given odd degree. As an application we also compute the formula for the one-level density for the zeros of these $L$-functions.
