Hi everybody, is there any Maple package to deal with algebraic curves? The problem I have to solve is the following: my thesis advisor gave me a polynomial equation in two variables, which I know it is a Riemann surface of genus 0. As far as I know, there is a theorem which says that this surface is birationally equivalent to an elliptic curve. There should be also an algorithm which receives the equation as input and outputs the rational parametrization of the Riemann surface. Moreover, this algorithm should be available in a Maple package (my advisor told me this... the problem is that he does not remember the name of the package, nor the function!!!).
