LCD codes and LCP of codes from units of group rings
A linear code with complementary dual(LCD) is a linear code such that LCD codes are of greatimportance due to their wide range of applications in consumer electronics,storage systems and cryptography. Group rings have a rich source of units. Alsothe well-

On the primitive irreducible representations of finitely generated nilpotent groups
We develop some tecniques whish allow us to apply the methods of commutative algebra for studing the representations of nilpotent groups. Using these methods, in particular, we show that any irreducible representation of a finitely generated nilpotent ...

On separable extensions of group rings and quaternion rings
The purposes of the present paper are (1) to give a necessary and sufficient condition for the uniqueness of the separable idempotent for a separable group ring extension RG(R may be a non-commutative ring), and (2) to give a full description of the set ...

Public Key Protocols over Skew Dihedral Group Rings
This paper introduces skew dihedral group rings and their applications for public-key cryptography. We present a specific skew group ring that is the underlying algebraic platform for our cryptographic constructions.

An associative ring \(R\) with identity is called left morphic if for every element \(a\in R\) there exists \(b\in R\) such that \(l_R(a)=Rb\) and \(l_R(b)=Ra\), where \(l_R(a)\) denotes the left annihilator of \(a\) in \(R\). The ring \(R\) is said to be strongly left morphic if every matrix ring \(M_n(R)\) is left morphic [\textit{W. K.

On Idempotent Units in Commutative Group Rings
Special elements as units, which are defined utilizing idempotent elements, have a very crucial place in a commutative group ring. As a remark, we note that an element is said to be idempotent if r^2=r in a ring. For a group ring RG, idempotent units are

Group Rings Satisfying Generalized Engel Conditions
Let R be a commutative ring with unity of characteristic r≥0 and G be a locally finite group. For each x and y in the group ring RG define [x,y]=xy-yx and inductively via [x ,_( n+1) y]=[[x ,_( n) y] , y].

When are the natural embeddings of classical invariant rings pure?
Consider a reductive linear algebraic group G acting linearly on a polynomial ring S over an infinite field; key examples are the general linear group, the symplectic group, the orthogonal group, and the special linear group, with the classical ...
