Let K be a finite field of characteristic p β‰₯ 5. The Nottingham group over K is the group of normalised automorphisms of the local field K t . In this paper we determine the automorphism group of ; in particular we show that every automorphism of the Nottingham group is standard. We also give a comp

We will show that for any integer n G 0, the automorphism group of an abelian p-group G, p G 3, contains a unique subgroup which is maximal with respect to being normal and having exponent less than or equal to p n . This subgroup is ⌸ l Fix p n G, where ⌸ is the unique maximal normal p-subgroup of
