  • Ticket #26487

    • Property Summary changed from isogenies_prime_degree() does not work well for degree = characteristic to Document that isogenies_prime_degree() only finds separable isogenies
    • Property Authors changed from to Jeroen Demeyer
  • Ticket #26487 – Description

    1 Depending on how ambitious one is, this is either a documentation bug or a missing feature. It seems that `isogenies_prime_degree` only finds separable isogenies, so it never finds the Frobenius. It does find the Verschiebung for ordinary elliptic curves but not for supersingular elliptic curves.
