Poonen's Project Description

Project: To compute the rank of the Mordell-Weil group of the Jacobian of the genus 2 curve

y2 = x6 - 2x5 - x4 + 4x3 + 3x2 + 2x + 1

over Q. If there is extra time, one can try also to find all the rational points on the curve, compute the rational torsion subgroup of the Jacobian, or the endomorphism ring of the Jacobian.
