16743 Extend IsogenyClass_EC to work over number fields cremona If E is an elliptic curve over QQ then E.isogeny_class() is an object of type (class) IsogenyClass_EC which which one can work in a nice way. This should be extended to number fields. Two reasons why this is notn-trivial (and hence was not done at the same time as over QQ): (1) bounding the possible primes degrees of isogenies; (2) handling curves with CM. For (1), the module {{{gal_reps_number_field}}} does what is required. For (2) new code has been written. enhancement closed major sage-6.4 elliptic curves fixed isogeny class John Cremona Jeroen Demeyer, Chris Wuthrich N/A 79fee2d40805b8278b9d0afeaccf50eb101990da 79fee2d40805b8278b9d0afeaccf50eb101990da #11327, #16764, #16806
