  • Ticket #11346 – Description

    initial v1  
    11Joanna Gaski found a serious bug in the function for computing conductors of elliptic curves over number fields, when the input curve is not integral.   Witness:
    22{{{
    3 sage: K.<g> = NumberField(x^2 - x - 1) #, embedding=1.6)
     3sage: K.<g> = NumberField(x^2 - x - 1)
    44sage: E1 = EllipticCurve(K,[0,0,0,-1/48,-161/864]); E1
    55Elliptic Curve defined by y^2 = x^3 + (-1/48)*x + (-161/864) over Number Field in g with defining polynomial x^2 - x - 1
