Query: On the structure of elliptic curves over finite extensions of
  $\mathbb{Q}_p$ with additive reduction   Let $p$ be a prime and let $K$ be a finite extension of $\mathbb{Q}_p$. Let
$E/K$ be an elliptic curve with additive reduction. In this paper, we study the
topological group structure of the set of points of good reduction of $E(K)$.
In particular, if $K/\mathbb{Q}_p$ is unramified, we show how one can read off
the topological group structure from the Weierstrass coefficients defining $E$.
