Abstract:Given an elliptic curve defined over a number field F , we study the algebraic structure and prove a control theorem for Wuthrich's fine Mordell-Weil groups over a Zp-extension of F , generalizing results of Lee on the usual Mordell-Weil groups. In the case where F " Q, we show that the characteristic ideal of the Pontryagin dual of the fine Mordell-Weil group over the cyclotomic Zp-extension coincides with Greenberg's prediction for the characteristic ideal of the dual fine Selmer group. If furthermore E has … Show more
