Title $p^{\infty}$-torsion subgroups of elliptic curves over $\mathbb{Z}_p$-extensions 2018-12-27 Jaehoon Lee(UCLA) 2018-12-27 KIAS 1424 Let L be a finite extension of $\mathbb{Q}_l$ for some odd prime l and let $L_{\infty}$ be a $\mathbb{Z}_p$-extension of L for some odd prime p. For an elliptic curve E over L, we completely classify all the cases when E($L_{\infty}$) [p^{\infty}] is finite. In the case when this group is infinite, we study its $\Lambda$-module structure and prove the pseudo-cyclicity.
