... curve in three points . Thus , the plane ax + by + cz + d = 0 meets the curve in the three points whose parametric values are the roots of the equation cu3 + bu2 + au + d = 0 . This cubic lies upon the three cylinders y = x2 , z = x3 ...

... curve. In the case of genus 1 one expects the compactification of M1 ∼= C1 to be P1. In fact if we set λ = 0 in the defining polynomial (7.3) of the elliptic curve and replace X by X + Z (which is a projective transformation) we get ...
