椭圆曲线的平均解析秩

The average analytic rank of elliptic curves

D. R. Heath-Brown

摘要:

本文的所有结果都是以椭圆曲线上的L-函数的黎曼假设为条件的。在此假设下,我们证明了Q上所有椭圆曲线的平均解析秩至多为2,从而改进了Brumer的一个结果.我们还表明,在任何家庭的二次扭曲的平均值是最多3/2,提高了Goldfeld的结果。第三个结果涉及的密度曲线的解析秩至少R,并表明,这种曲线的比例下降速度比指数R增长。证明依赖于Weil的“显式公式”的一个类似物。

英文摘要:

All the results in this paper are conditional on the Riemann Hypothesis for the L-functions of elliptic curves. Under this assumption, we show that the average analytic rank of all elliptic curves over Q is at most 2, thereby improving a result of Brumer. We also show that the average within any family of quadratic twists is at most 3/2, improving a result of Goldfeld. A third result concerns the density of curves with analytic rank at least R, and shows that the proportion of such curves decreases faster than exponentially as R grows. The proofs depend on an analogue of Weil's ``explicit formula''.
