We argue that for all integers $N \geq 2$ and $g \geq 1$ there exist multiradical isogeny formulae, that can be iteratively applied to compute $(N^k, \ldots, N^k)$-isogenies between principally polarized $g$-dimensional abelian varieties, for any value

Isogenies on Kummer Surfaces [PDF]
We first give a cleaner and more direct approach to the derivation of the Fast model of the Kummer surface. We show how to construct efficient ( N ,

In this paper, we apply Tsuzuki’s main theorem in [12] to establish a criterion for when two abelian varieties over a function field $K$ of characteristic $p$ are isogenous. Specifically, assuming that their endomorphism algebras tensored with $\mathbb{Q}

On the Efficient Representation of Isogenies
We survey different (efficient or not) representations of isogenies, with a particular focus on the recent "higher dimensional" isogeny representation, and algorithms to manipulate them.

Radical Isogenies on Montgomery Curves [PDF]
We work on some open problems in radical isogenies. Radical isogenies are formulas to compute chains of $N$-isogenies for small $N$ and proposed by Castryck, Decru, and Vercauteren in Asiacrypt 2020.

Fast computation of 2-isogenies in dimension 4 and cryptographic applications [PDF]
Dimension 4 isogenies have first been introduced in cryptography for the cryptanalysis of Supersingular Isogeny Diffie-Hellman (SIDH) and have been used constructively in several schemes, including SQIsignHD, a derivative of SQIsign isogeny based ...

Horizontal racewalking using radical isogenies [PDF]
We address three main open problems concerning the use of radical isogenies, as presented by Castryck, Decru and Vercauteren at Asiacrypt 2020, in the computation of long chains of isogenies of fixed, small degree between elliptic curves over finite ...
