二维阿贝尔簇的自同态环的计算

Computing endomorphism rings of abelian varieties of dimension two

Gaetan Bisson

摘要:

推广了Sutherland和作者的椭圆曲线方法,设计了一个计算有限域上二维普通阿贝尔簇自同态环的次指数算法.虽然它的正确性和复杂性分析依赖于几个假设,我们报告的实际计算表明,它的表现非常好,可以很容易地处理以前棘手的情况。

英文摘要:

Generalizing a method of Sutherland and the author for elliptic curves, we design a subexponential algorithm for computing the endomorphism rings of ordinary abelian varieties of dimension two over finite fields. Although its correctness and complexity analysis rest on several assumptions, we report on practical computations showing that it performs very well and can easily handle previously intractable cases.
