On Properties of Graded Rings with respect to Group Homomorphisms
Let G be a group and R be a G-graded ring with non-zero unity. The goal of our article is reconsidering some well-known concepts on graded rings using a group homomorphism α:G⟶G. Next is to examine the new concepts compared to the known concepts.

Periodic rings with finitely generated underlying group
We study periodic rings that are finitely generated as groups. We prove several structure results. We classify periodic rings that are free of rank at most 2, and also periodic rings R such that R is finitely generated as a group and R/t(R)≃ℤ.

On group rings and some of their applications to combinatorics and symmetric cryptography [PDF]
We give a survey of recent applications of group rings to combinatorics and to cryptography, including their use in the di erential cryptanalysis of block ciphers.

Let \(G\) be an additive group (not necessarily Abelian) with identity \(0\). The set \(M_0(G)\) of all \(0\)-preserving functions from \(G\) to itself forms a near-ring under pointwise addition and composition of functions. If \(R\subseteq M_0(G)\) is a ring under these operations, then \(R\) is said to be a `subring' of \(M_0(G)\).

Finite Dimensional Group Rings [PDF]
A ring is right finite dimensional if it contains no infinite direct sum of right ideals. We prove that if a group G is finite, free abelian, or finitely generated abelian, then a ring R is right finite dimensional if and only if the group ring RG is right finite dimensional.

Sylow like theorems for V(ZG) [PDF]
The main part of this article is a survey on torsion subgroups of the unit group of an integral group ring. It contains the major parts of my talk given at the conference "Groups, Group Rings and Related Topics" at UAEU in AlAin October 2013.

Unique eleven-membered rings containing silicon, germanium, and tin were synthesized in good yields by the reactions of the corresponding 1,2-bis((2-bromothiophen-3-yl)methoxy)benzenes with (C6H5)2ECl2 where E = Sn, Ge, Si.

On Azumaya Galois extensions and skew group rings
Two characterizations of an Azumaya Galois extension of a ring are given in terms of the Azumaya skew group ring of the Galois group over the extension and a Galois extension of a ring with a special Galois system is determined by the trace of the Galois
