有限域上迹函数短和的高斯分布

Gaussian distribution of short sums of trace functions over finite fields

Corentin Perret-Gentil

摘要:

我们证明了在一定的一般条件下,当原点变化时,有限域上$\ell$ -adic迹函数的短和渐近服从正态分布,推广了Erdens-Davenport,Mak-Zaharescu和Lamzouri的结果.特别是,这适用于指数和所产生的傅里叶变换,如Kloosterman和或伯奇和,因为我们可以推断,从工程卡茨。通过近似单值群中随机矩阵迹的矩,可以给出一个定量的版本,如Lamzouri的文章中所述,表现出与中心极限定理的平均不同的现象。

英文摘要:

We show that under certain general conditions, short sums of $\ell$-adic trace functions over finite fields follow a normal distribution asymptotically when the origin varies, generalizing results of Erdős-Davenport, Mak-Zaharescu and Lamzouri. In particular, this applies to exponential sums arising from Fourier transforms such as Kloosterman sums or Birch sums, as we can deduce from the works of Katz. By approximating the moments of traces of random matrices in monodromy groups, a quantitative version can be given as in Lamzouri's article, exhibiting a different phenomenon than the averaging from the central limit theorem.
