Abstract
We describe all the elliptic fibrations with section on the Kummer surface X X of the Jacobian of a very general curve C C of genus 2 2 over an algebraically closed field of characteristic 0, modulo the automorphism group of X X and the symmetric group on the Weierstrass points of C C . In particular, we compute elliptic parameters and Weierstrass equations for the 25 different fibrations and analyze the reducible fibers and Mordell–Weil lattices. This answers completely a question posed by Kuwata and Shioda in 2008.
