任意特征的显式Kummer曲面理论

Explicit Kummer surface theory for arbitrary characteristic

Jan Steffen Müller

摘要:

我们明确地找到了一个方程和一个与亏格为2的曲线的雅可比矩阵相关联的库默尔曲面的射影嵌入,该曲线由任意基域上的形式为y ^2 + h(x)y = f(x)的方程给出,以及几个可用于对其进行算术运算的映射。这扩展了Flynn的早期工作,并具有应用,例如,在亏格2雅可比行列式的规范高度计算和密码学中。

英文摘要:

We explicitly find an equation and a projective embedding of the Kummer surface associated to the Jacobian of a curve of genus 2 given by an equation of the form y^2 + h(x)y = f(x) over an arbitrary ground field as well as several maps that can be used to perform arithmetic on it. This extends earlier work by Flynn and has applications, for instance, in computations of canonical heights for genus 2 Jacobians and in cryptography.
