$2$-adic Representations of Elliptic Curves over $\mathbb{Q}_2$

Source abstract

We provide a complete classification of the rational $2$-adic Tate modules $V_2(E)$ of elliptic curves $E/\mathbb{Q}_2$ with potentially good reduction. The classification is given in terms of the filtered $(\varphi,\mathrm{Gal})$-modules associated to $V_2(E)$ via Fontaine's functor $D_{pcris}^{*}$.
