2024-02-05 15:43:03 +0200 answered a question Frobenius Endomorphism of Finite field Elliptic curve for elements

Starting from Sage 9.8, you can simply write .frobenius_endomorphism() to construct the Frobenius endomorphism (over the

2024-02-05 15:43:03 +0200 answered a question Compute elements of n-torsion group of elliptic curve over finite field

Nowadays, you can use .division_field() to find the minimal extension where the full $\ell$-torsion is defined, and .tor

2024-02-05 15:43:03 +0200 answered a question Rational maps for a composed isogeny

Starting from Sage 9.8, writing f.rational_maps() just works.

2024-02-05 15:43:02 +0200 answered a question How to construct an isogeny [i] such that [i]^2= -1?

Starting from Sage 10.3, you can use next(a for a in E.automorphisms() if a^2 == -1).
