Period and index of genus one curves over number fields

Shahed Sharif

摘要:

曲线的周期是Galois-不变因子类的最小正次数。该指数是有理因子的最小正度。我们构造了给定数域上具有指定周期和指数的亏格为1的曲线的例子。

英文摘要:

The period of a curve is the smallest positive degree of Galois-invariant divisor classes. The index is the smallest positive degree of rational divisors. We construct examples of genus one curves with prescribed period and index over certain number fields.
