Descent calculations for the elliptic curves of conductor 11
|
Let A be one of the three elliptic curves over Q
with conductor 11. We show that A has Mordell-Weil rank zero over
its field of 5-division points. In each case we also compute the
5-primary part of the Tate-Shafarevich group. Our calculations make use
of the Galois equivariance of the Cassels-Tate pairing.
