I am not an expert, but is it normal to get negative canonical height of a point on elliptic curve over number field?
sage: Z1.<Z>=ZZ[];Nf.<v>=NumberField(Z**16-2);E=EllipticCurve(Nf,[-87, 504, -40320, 0, 0]);P=E(0,0) sage: P.height() #not very fast -0.150688795814905 sage: P.height(precision=2000) -0.15068879581490624...<snip> Works on cloud.sagemath too. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
