其中Λ是C中的晶格。这个同构是C上解析群的同构,它可以用Weierstrass函数明确地描述。同构(1.1)为椭圆曲线的研究提供了一个强有力的工具;作为一个简单的例子,注意(1.1)意味着对任何n ≥ 2,E的n-torison同构于(1/n)Λ/Λ(Z/nZ)×(Z/nZ),这不容易用纯代数方法证明。
where Λ is a lattice in C. This isomorphism is an isomorphism of analytic groups over C, which can be explicitly described using the Weierstrass ℘-function. The isomorphism (1.1) gives a powerful tool for the study of elliptic curves; as a simple example, note that (1.1) implies that for any n ≥ 2 the n-torison of E is isomorphic to (1/n)Λ/Λ ≈ (Z/nZ)×(Z/nZ), which is not so easy to prove with purely algebraic methods.
