初等3-下降与3-等距
Elementary 3-descent with a 3-isogeny
摘要：
在本文中，我们展示了如何在实践中使用3-下降与3-等距找到一个估计的秩的椭圆曲线有一个合理的3-挠子群，我们也给这些计算的几何解释。
英文摘要：
In this expository paper, we show how to use in practice 3-descent with a 3-isogeny to find an estimate for the rank of an elliptic curve having a rational 3-torsion subgroup, and we also give a geometric interpretation of these computations.
