椭圆曲线上的几乎全复点

Almost totally complex points on elliptic curves

Xavier Guitart, Victor Rotger, Yu Zhao

摘要:

设$F/F_0$是全实数域的二次扩张,$E$是$F$上的椭圆曲线,它与$F_0$上的Galois共轭同构.一个二次扩张$M/F$称为几乎全复(ATC),如果$F$的所有阿基米德位除一个外都扩张到$M$的复位。本文的主要目的是在$E$上提供一个新的Darmon样点的构造,这些点是在$M$的某些环类域上定义的。这些点是通过扩展达蒙的ATR方法构造的高维模阿贝尔簇,从他们继承了以下特点:他们是代数提供达蒙的ATR点的代数保持真实,他们是明确可计算的,我们说明了一个详细的例子,提供了一定的数值证据,我们的代数的有效性。

英文摘要:

Let $F/F_0$ be a quadratic extension of totally real number fields, and let $E$ be an elliptic curve over $F$ which is isogenous to its Galois conjugate over $F_0$. A quadratic extension $M/F$ is said to be almost totally complex (ATC) if all archimedean places of $F$ but one extend to a complex place of $M$. The main goal of this note is to provide a new construction of a supply of Darmon-like points on $E$, which are conjecturally defined over certain ring class fields of $M$. These points are constructed by means of an extension of Darmon's ATR method to higher dimensional modular abelian varieties, from which they inherit the following features: they are algebraic provided Darmon's conjectures on ATR points hold true, and they are explicitly computable, as we illustrate with a detailed example that provides certain numerical evidence for the validity of our conjectures.
