Returns true if and only if the given polynomial, sequence of polynomials, or matrix determines a "genus one model" in the sense described in the introduction to this chapter. When true, the model is also returned.Important note: This does not imply that the associated scheme is a curve of genus 1, as degenerate cases are allowed!
Return true if and only if the two given cubics (or genus one models of degree 3) are equivalent as genus one models. In other words, that there exists a linear transformation of the ambient projective space PQ2 which takes one cubic to the other, up to scaling. The algorithm is given in [Fis06].[Next][Prev] [Right] [Left] [Up] [Index] [Root]When true, the transformation is also returned as a tuple (the syntax is explained in Section Transformations between Genus One Models, on transformations, below).
