Normal Bases on Galois Ring Extensions [PDF]

open access: yesSymmetry, 2018
In this paper we study the normal bases for Galois ring extension ${{R}} / {Z}_{p^r}$ where ${R}$ = ${GR}$(pr, n). We present a criterion on normal basis for ${{R}} / {Z}_{p^r}$ and reduce this problem to one of finite field extension $\overline{R} / \overline{Z}_{p^r}=F_{q} / F_{p}  (q=p^n)$ by Theorem 1. We determine all optimal normal bases

Multiplication in a Galois ring

2015 Seventh International Workshop on Signal Design and its Applications in Communications (IWSDA), 2015
In this paper, we focus on the efficient multiplication in a Galois ring of the size 4n, where n is a positive integer. We consider to adapt the finite field multiplication methods to the Galois ring multiplication. We give the polynomial multiplication in the Galois ring as a Toeplitz matrix-vector multiplication design with a modification used in ...

Galois-Azumaya extensions and the Brauer-Galois group of a commutative ring

open access: yesBulletin of the Belgian Mathematical Society - Simon Stevin, 2006
We attach to any commutative ring R a subgroup of the Brauer group of R, called the Brauer-Galois group of R. Its elements are the classes of the Azumaya R-algebras which can be represented, via Brauer equivalence, by a Galois extension of R. We compute this group for some particular commutative fields.

Witt Rings and Galois Groups

The Annals of Mathematics, 1996
This paper is concerned with the connections between the Witt ring of a field and the structure of certain Galois extensions of that field. In particular, it is shown that the Witt ring determines, and is determined by, the Galois group of a certain 2-extension of the field (with an unavoidable uncertainty over the characteristic of the Witt ring in ...
