Descent Via Isogeny on Elliptic Curves with Large Rational Torsion Subgroups.
We outline PARI programs which assist with various algorithms related to descent via isogeny on elliptic curves. We describe, in this context, variations of standard inequalities which aid the computation of members of the Tate-Shafarevich group. We apply these techniques to several examples: in one...
