AbstractLet K be a field of characteristics 0 complete with respect to a discrete valuation v, with a perfect residue field of characteristic p>0. Let
$$\vec K$$
be an algebraic closure of K and Knr its maximal unramified subextension. Let E be an elliptic curve over K with an integral modular invariant. The curve E has potentially good reduction at v, and there exists a smallest extension L of Knr over which E has good reduction at v. The Galois group, Gal (L/Knr) is known in the case p≥5. In this paper we give receipts to determine this group in the cases p=2 and p=3.
