Let K be a finite field of characteristic p ≥ 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

✦ Synopsis
The aim of this paper is to show that the automorphism and isometry groups of the suspension of B(H), H being a separable infinite-dimensional Hilbert space, are algebraically reflexive. This means that every local automorphism, respectively, every local surjective isometry, of C 0 (R) B(H) is an automorphism, respectively, a surjective isometry.

An infinite circulant digraph is a Cayley digraph of the cyclic group of Z of integers . Here we prove that the full automorphism group of any strongly connected infinite circulant digraph over minimal generating set is just the group of translations of Z . We also present some related conjectures .
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
