高斯超几何函数的Distribution of values

Distribution of values of Gaussian hypergeometric functions

Ken Ono, Hasan Saad, Neelam Saikia

摘要:

在20世纪80年代,格林用雅可比和定义了{有限域上的\it超几何函数}。他的理论框架建立,这些职能具有许多性质,类似于那些经典的超几何级数研究高斯和库默尔。这些函数在Apéry式超同余、Eichler-Selberg迹公式、伽罗瓦表示和算术簇的zeta函数的研究中发挥了重要作用。我们研究了这些函数的自然族的值分布(在大的有限域上)。对于$_2F_1$函数,极限分布是半圆形的(即$SU(2)$),而对于实正交群$O_3$的迹,$_3F_2$函数的分布是{ \it Batman}分布。

英文摘要:

In the 1980's, Greene defined {\it hypergeometric functions over finite fields} using Jacobi sums. The framework of his theory establishes that these functions possess many properties that are analogous to those of the classical hypergeometric series studied by Gauss and Kummer. These functions have played important roles in the study of Apéry-style supercongruences, the Eichler-Selberg trace formula, Galois representations, and zeta-functions of arithmetic varieties. We study the value distribution (over large finite fields) of natural families of these functions. For the $_2F_1$ functions, the limiting distribution is semicircular (i.e. $SU(2)$), whereas the distribution for the $_3F_2$ functions is the {\it Batman} distribution for the traces of the real orthogonal group $O_3$.
