Cubic AGM graphs and Hessian $3$ -isogenies over finite fields $F_{q}$ of odd characteristic with $q \equiv 2 (mod 3)$

Yuji Hashimoto, Koji Nuida

Let $F_{q}$ be a finite field of odd characteristic with $q \equiv 2 (mod 3)$ . We study the directed graph defined by the Borwein--Borwein cubic arithmetic--geometric mean (A…

Ordinary 3-Isogeny Graphs and Improvement of Supersingularity Testing for Twisted Hessian Curves over Prime Fields

Yuji Hashimoto, Koji Nuida

For any primes $p \neq = ℓ$ , $ℓ$ -isogeny graphs of ordinary elliptic curves defined over $F_{p^{2}}$ have a typical structure called $ℓ$ -volcanoes, and the structure…
