How do you compute the conductor of an elliptic curve (over
)
in Sage?
Once you define an elliptic curve
in Sage, using the
EllipticCurve
command, the conductor is one of several
``methods'' associated to
. Here is an example of the syntax
(borrowed from section
2.4 ``Modular forms'' in the tutorial):
sage: E = EllipticCurve([1,2,3,4,5]) sage: E Elliptic Curve defined by y^2 + x*y + 3*y = x^3 + 2*x^2 + 4*x + 5 over Rational Field sage: E.conductor() 10351
