函数域上椭圆曲线L函数零点的独立性

Independence of the zeros of elliptic curve L-functions over function fields

Byungchul Cha, Daniel Fiorilli, Florent Jouve

摘要:

线性无关假设(LI),它大致说明了Dirichlet L函数的临界零点的虚部在有理数上是线性无关的,在素数族的研究中有着有趣的结果,正如Rubinstein和Sarnak所指出的。本文证明了在某些椭圆曲线L函数族及其对称幂内,LI的函数域模拟一般成立.更确切地说,对于某些代数几何族的椭圆曲线定义在一个有限域上的固定曲线的函数域,我们给出了强的定量界的元素的数量在家庭中的相关L函数有其零点线性无关的有理数尽可能。

英文摘要:

The Linear Independence hypothesis (LI), which states roughly that the imaginary parts of the critical zeros of Dirichlet L-functions are linearly independent over the rationals, is known to have interesting consequences in the study of prime number races, as was pointed out by Rubinstein and Sarnak. In this paper, we prove that a function field analogue of LI holds generically within certain families of elliptic curve L-functions and their symmetric powers. More precisely, for certain algebro-geometric families of elliptic curves defined over the function field of a fixed curve over a finite field, we give strong quantitative bounds for the number of elements in the family for which the relevant L-functions have their zeros as linearly independent over the rationals as possible.
