The 3-adic representations arising from elliptic curves over $\mathbb{Q}_3$ with potential good reduction

Abstract

We give a complete classification of all the potentially crystalline 3-adic representations of the absolute Galois group of $\mathbb{Q}_3$ that are isomorphic to the Tate module of an elliptic curve defined over $\mathbb{Q}_3$. These representations are described in terms of their associated filtered $(\varphi, \mathrm{Gal}(K/\mathbb{Q}_3))$-modules. The most interesting cases occur when the potential good reduction is wild.
