三次域的计数函数中的次项

Secondary terms in counting functions for cubic fields

Takashi Taniguchi, Frank Thorne

摘要:

本文证明了三次域上Davenport-Heilbronn定理和二次域类群中3-挠定理中X^{5/6}阶次项的存在性。对于立方域,这证实了Datskovsky-Wright和Roberts的一个猜想。我们还证明了各种推广,包括等差数列,在那里我们发现了一个奇怪的偏见,在第二任期。罗伯茨猜想也被Bhargava、Shankar和Tsimerman独立证明。与他们的工作相反,我们的证明使用与二元三次型空间相关的zeta函数的分析理论,由Shintani和Datskovsky-Wright开发。

英文摘要:

We prove the existence of secondary terms of order X^{5/6} in the Davenport-Heilbronn theorems on cubic fields and 3-torsion in class groups of quadratic fields. For cubic fields this confirms a conjecture of Datskovsky-Wright and Roberts. We also prove a variety of generalizations, including to arithmetic progressions, where we discover a curious bias in the secondary term. Roberts' conjecture has also been proved independently by Bhargava, Shankar, and Tsimerman. In contrast to their work, our proof uses the analytic theory of zeta functions associated to the space of binary cubic forms, developed by Shintani and Datskovsky-Wright.
