Let \(RG\) be the group ring of a group \(G\) over an associative ring \(R\) with identity. In this paper the considered modules are unitary. Let \(\mathrm{Hom}_R(M_R,N_R)\) be the set of all \(R\)-homomorphisms between two right \(R\)-modules \(M_R\) and \(N_R\).

J-Boolean group rings and skew group rings
Journal of Algebra and Its Applications, 2018A ring [Formula: see text] is called semiboolean if [Formula: see text] is boolean and idempotents lift modulo [Formula: see text], where [Formula: see text] denotes the Jacobson radical of [Formula: see text]. In this paper, we define [Formula: see text]-boolean rings as a generalization of semiboolean rings.

Integral Group Rings of Finite Groups
Canadian Mathematical Bulletin, 1967The main object of this paper is to show that the existence of a particular kind of isomorphism between the integral group rings of two finite groups implies that the groups themselves are isomorphic. The proof employs certain types of linear forms which are first discussed in general.
