Computing isogenies between jacobians of hyperelliptic curves of arbitrary genus via differential equations

Elie Eid

摘要:

设$p$为奇素数,且为与$p$互质的整数.本文研究了$p$ -进数域$\mathbb{Q}\_p$的扩张$K$上任意亏格的超椭圆曲线的Jacobian之间的$(\ell,...,\ell)$ -同构的显式有理表示的算法.该算法在$\ell$和曲线的亏格上都具有拟线性复杂度。

英文摘要:

Let $p$ be an odd prime number and be an integer coprime to $p$. We survey an algorithm for computing explicit rational representations of $(\ell,...,\ell)$-isogenies between Jacobians of hyperelliptic curves of arbitrary genus over an extension $K$ of the field of $p$-adic numbers $\mathbb{Q}\_p$. The algorithm has a quasi-linear complexity in $\ell$ as well as in the genus of the curves.
