Free products in the unit group of the integral group ring of a finite group [PDF]
, 2016 Let $G$ be a finite group and let $p$ be a prime. We continue the search for generic constructions of free products and free monoids in the unit group $\mathcal{U}(\mathbb{Z}G)$ of the integral group ring $\mathbb{Z}G$.

From the Poincaré Theorem to generators of the unit group of integral group rings of finite groups [PDF]
Mathematics of Computation, 2013 We give an algorithm to determine finitely many generators for a subgroup of finite index in the unit group of an integral group ring $\mathbb{Z} G$ of a finite nilpotent group $G$, this provided the rational group algebra $\mathbb{Q} G$ does not have ...

Short Principal Ideal Problem in multicubic fields
Journal of Mathematical Cryptology, 2020 One family of candidates to build a post-quantum cryptosystem upon relies on euclidean lattices. In order to make such cryptosystems more efficient, one can consider special lattices with an additional algebraic structure such as ideal lattices.

On Idempotent Units in Commutative Group Rings
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2020 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

Unit groups of integral group rings [PDF]
Proceedings of the American Mathematical Society, 1994 Let U ( Z G ) U(\mathbb {Z}G) be the unit group of the integral group ring Z G \mathbb {Z}G . A group G G satisfies ( ∗ ) ({\ast }) if either the set
