Dear All, Let $C$ be the following curve in $\mathbb{C}^2$. \begin{align} & 11664 {c_1}^3 {c_2}^2 + 536544 {c_1}^3 c_2 + 6170256 {c_1}^3 + 67068 {c_1}^2 {c_2}^2 + 1542564 {c_1}^2 c_2 \\ & + 3085128 c_1 {c_2}^2 - 32393844 c_1 c_2 + 3085128 c_1 + 17739486 {c_2}^2 + 6941538 c_2 = 0. \end{align} I checked that this curve has genus $1$ using Sage. Therefore it is an elliptic curve. How to change coordinates such that the equation of this curve is of the form $y^2 = f(x)$, where $f$ is some polynomial. Thank you very much.
I tried to use the following codes in Sage. R.<c1,c2> = QQ[]; Jacobian(11664*c1^3*c2^2 + 536544*c1^3*c2 + 6170256*c1^3 + 67068*c1^2*c2^2 + 1542564*c1^2*c2 + 3085128*c1*c2^2 - 32393844*c1*c2 + 3085128*c1 + 17739486*c2^2 + 6941538*c2) But there is an error: NoEmbeddingError: not a sub-polytope of a reflexive polygon. How to find the normal form of this curve using Sage? Thank you very much. Best regards, Jianrong. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
