If F is an algebraic number field of degree n over Q and p is a prime, then F is p-realizable if there is a tor-sionfree abelian group A of rank n such that qA = A for all prines q i p and F is isomorphic to the quasi-endomorphism algebra of A. The question “for which F and p is F p-realizable?” was the subject of the paper by Pierce and Vinsonhaler ...

Reconfigurable Galois Field multiplier
2014 International Symposium on Biometrics and Security Technologies (ISBAST), 2014Galois Field has received a lot of attention because of their important and particular applications in cryptography, channel coding, etc. This paper presents the Reconfigurable Galois Field multiplier used to calculate the Galois field multiplication of different lengths which consists of AND gates and special cells.

HOPF–GALOIS STRUCTURES ON FIELD EXTENSIONS WITH SIMPLE GALOIS GROUPS
Bulletin of the London Mathematical Society, 2003Let \(L/K\) be a Galois extension of fields with Galois group \(G\). Then the group ring \(KG\) endows \(L/K\) with a Hopf Galois structure. There may be other \(K\)-Hopf algebras \(H\) endowing \(L/K\) with a Hopf Galois structure; all of them are forms of group rings over \(L\).

Field Theory of Galois' Fields
1995The motivation for the present work comes from various sources which, however, need not be elaborated on here. I will be exploring a class of quantum field theories defined over finite sets of integers. Essentially these are the familiar Z„ lattice theories, but carried to their logical extremes.

Consider an algebraic system \(\langle SF, +, \cdot \rangle\) consisting of a finite set of elements, \(SF\) with two binary operations, addition and multiplication, \(|SF|=q\), \(q\) an arbitrary integer \(\geq 2\). A spurious Galois field, \(SGF(q)\) satisfies, in addition, the following axioms: A.1.

This chapter is devoted to the theory of fields, Galois theory, geometric constructions by ruler and compass, and the theorem of Abel–Ruffini about the polynomial equations of degree \(n, n\ge 5\). We also discuss cubic and biquadratic equations.

1974
The first principal theme of this chapter is the structure theory of fields. We shall study a field F in terms of a specified subfield K (F is said to be an extension field of K). The basic facts about field extensions are developed in Section 1, in particular, the distinction between algebraic and transcendental extensions.
